Cisco ASR 1000 Router

Aug 2, 2009

I'm buying Cisco ASR 1000 router that should handle 2 Gbps bandwidth. Please advice on components, models, etc.

I have a vendor, but I'll appreciate any reference, based on your experience, on where to buy one at reasonable price. I think I can probably get refurbished ASR 1000 or similar as well, if the vendor can guarantee the quality of the device.

Which Cisco Router To Use

Jul 11, 2007

I am currently looking at these Cisco switches:

- Cisco 2924 WS-C2924-XL-EN Enterprise Switch
- Cisco 2950 WS-C2950-24 Catalyst Switch
- Cisco 3512 WS-C3512-XL-EN Enterprise Switch
- Cisco 3524 WS-C3524-XL-EN Enterprise Switch
- Cisco 3548 WS-C3548-XL-EN Enterprise Switch

1) I was recommended to chose the XL-EN model switches because it seems they have more Memory, but the second one in the list (Catalyst) is not a XL-EN, is that going to have any affect performance wise? or it doesn't really matter?

2) I was also recommended to choose managed switches because that way I can use the SNMP features to measure bandwidth, are any of the switches above unmanaged?

3) I also want to be able to manage the switch remotely, web managed, are any of the switches above web-manageable?

4) Most importantly, when my datacenter give me a 100mbit drop, I dont know which port to plug it in in the 29** series. In the 35** I see it clearly but I am not able to see it in the 29**, any ideas?

5) On some of these switches I see a special port called "Console", what is it? where does that connect to?

6) Do any of the switches above not have a console port?

Cisco Router For Terminating SMF SC Interface

Sep 9, 2009

I have a requirement where one of our partner is planning to connect to our datacenter using a dedicated leased line.

As per our partner, they will engage a Leased line vendor for this. This vendor will terminate the leased line ( Single mode fiber -- SC connector) to the Comm room of our Colocation provider.

I have next to nothing knowledge about fiber connectivity and have few questions in this regard.

Q1. If Single mode fiber is terminated at COLO's Comm room in form of SMF SC connector, what kind of cross connect should we request from COlo's comm room to our cabinet. ( SMF / MMF )

Q2. How are these cross connects terminated in cabinet? Do Colo provider use some kind of fiber patch panel or they simply provide a fiber link with SC/LC connectors at the end of it?

Q3. If cross connect needs to be SMF SC then which cisco routers support SMF SC interfaces? Do I need SC-LC patch cable?

(I looked at the various option but could only find the following GLC-LH-SM or GLC-ZX-SM for SMF connectivity. I read about these and found that GLC-LH-SM is used for terminating single mode fiber that spans up to 10 km and GLC-ZX-SM is used for terminating single mode fiber that spans up to 70 km in length. It looks as if both of these support LC connectors. Are these the only two SMF connectivity options? Do I need SC-LC patch cable )

Q4. Our partner only tells us that the terminated link will be terminated using SMF SC. How to figure out if GLC-LH-SM or GLC-ZX-SM is required.

Leasing A Cisco 7301 Router

Jan 27, 2007

The Cisco 7301 has 3 integrated Gig-E ports and one empty slot which we'll use with an OC3 SMI PA for a handoff to SAVVIS. (when will they ever go to Ethernet handoff?)

Is anyone here leasing a Cisco 7301 router, who can comment on the approximate monthly lease cost? I know the approximate retail cost, but can't really guess on the residual after 3, 4, or 5 year lease, so it's hard to estimate the approximate payment to expect. I don't want to get a salesperson involved yet because once they have your phone #, they never stop calling, and I'm not 100% certain we're going with the 7301 (versus a Juniper M5 or M7i).

Capabilities Of Cisco 7206 VXR Router

Feb 17, 2007

I've been shopping for routers, and I'm curious as to the capabilities of a Cisco 7206 VXR Router. Would an NPE-300 or NPE-400 be capable of running three BGP sessions for 100 Mbps? At what point would it start topping out bandwidth wise? How much RAM would be recommended? Is a PE-GE good enough for the connections that are delivered by gigabit ethernet?

I realize that some of you may be inclined to recommend talking to a network consultant, but at this stage that's probably premature. I'm in a planning stage at this point.

Fire sale at HE on used Cisco core router equipment

I wonder if some data center will purchase it just to hook it up for the flashing lights... would be quite impressive.
Wait a second, that was already done in North Atlanta and Las Vegas, wasnt it?

I wonder why HE didnt donate it to the tech museum in San Jose... would have been a better write off then selling it.

why I am musing so far off topic on a gorgeous Sunday morning?

Cisco IOS Router Vs. ASA Firewall For Small Colo-racked Setup

May 3, 2008

I am in the process of gathering the peices to move from a dedicated box to my own hardware in a local colo and am undecided how best to choose the edge device.

The colo has a 30Mb pipe with about 10Mb of it being constantly used during biz hours. Another 10Mb is being allocated in the next couple of months. I want to be able to burst to the full 30Mb when needed.

I am getting 12 IP's allocated but will increase to 24 soon if all goes well (fingers crossed!).

I will have for starters just a single Proliant running dnp on 2008 with IIS, FTP, Mail, ns1 and a 2003 VM running my secondary ns.

What I am unsure of is the edge device and looking for others that have used either a 2800 series router or a ASA5500 series firewall in a similiar fashion. I know what the raw throughput of each device is, but raw benchmarks are not realworld numbers by any means.

I am looking at the 2801 with IOS Firewall turned on and hopefully even some inspects for FTP and HTTP traffic. The other option and one that I am less familiar with is to use the ASA5505 instead which will do my basic routing but supposedly provide more thourough inspects and advanced rules.

Does anyone have experiance with either of these in a hosting environment and have input on the realistic throughput one can expect from either device?

There is a signifigant cost difference with the ASA5505 being much cheaper but I am more familiar with IOS. Would anyone recommend a 1841 router instead?

Router

May 26, 2007

I am having a big question which has been often asked, but which all the time depends on the network topology; so first let's be honnest :

- I have no experience with BGP / OSPF
- I have no experience with routers (except SOHO models
- I will not have to make this to work in a productive environment

So in the next month we will get an AS number and few IP addresses; the goal is to test drive a gigabit network before using it as productive network;

I would like to ask some advices here for early all aspecsts, let's show some important points :

- Which brand?
- Which model?
- Maybe refurbished?

The key points for me:

I am looking for a cheap chasis but extensible with time when it will be needed

- Extensible system
- Very cheap for small use (at beginning maximum $ 2-3k)
- Trafic rate : ~ 100 MBit/s to 4-5 GBit/s
- Type of trafic : HTML / JPG / GIF / PNG / CSS / EXE / ZIP (shared hosting network)

Router

Feb 21, 2007

getting my own AS number, but this seems to require also a router. I don’t really have a strong knowledge of routing, just basic knowledge.

As I think I understood, I have two possibilities for routing, to buy a ready-made router (Cisco, Juniper, Nortel,…) or to simply setup a simple box with Linux or BSD OS, some NIC and use a software such as Zebra, Quagga, etc…

So my question is :

- Is it possible to use for professional purposes a BSD box with Zebra ?
- What is entry price for a good Cisco router (approximately) ?
- Does BASIC routing setup requires a very strong knowledge ?

In case this would became concrete soon, people answering could maybe get some paid work doing this for us.

IP And Router

Jan 10, 2007

I regiested a IP address from one company and I can post my website on internet. that company give me an IP address someting like: 167.23.42.100. Right now My internet speed is very slow, I want to reset my router. If I reset my router, router will produce a new IP address, Does this IP address is same as 167.23.42.100. IF i reset router, do i need to change my website address. I am worry that resetting router will affect my website address(domin name).

Maybe router IP is different as doman name. so I don't need to worry about

A Multiple WAN Router

May 17, 2009

I am looking for a good router which will handle two separate WAN connections and bridge them together. Basically, we have DSL at our office (1.5mbps down / 769kbps up), its the only service we can get, cable is not offered, and a T1 inst fast enough and costs too much. We require a faster connection, doing Skype, VPN connections to servers, desktop sharing etc.

Basically we want to order another DSL line 1.5mbps down / 768 kbps up and join it together with our current DSL connection for a total of 3mbps down/1.5mbps up.

Just want to make sure this is possible and if you guys can recommend a router brand and model. To clerify, we don't just want redunacy/fail over, we need to utilize both DSL connections at the same, as if they were one.

Mutliple WAN Router

May 19, 2009

We are looking for a good multiple WAN router for our office. We just ordered two DSL 3.0mbps down / 768kbps up lines.

Here are the requirements:

--> Under $500

--> 2 WAN Load Balanced And Fail Over Support

--> Smart enough to handle special session state traffic. Example, if you start a HTTPS session on one DSL line it has to stay on that line. If you start an FTP session connection on one line it has to stay on that line.

--> VPN Tunnel Site-To-Site Support, Only need a max of 1 site-to-site tunnel, but nice to have more just in case.

--> Standard SPI Firewall With Port Forwarding

--> Reserve LAN Static IP's

--> Firewall throughput of at least 10mbps

Router VS Switch

Feb 13, 2008

We have a small hosting company (currently 24 racks) that we are expanding to hold 100 racks. We have several 3640 series routers behind a 7200 series router (our edge router) that feed into numerous 2950 switches and 515 & 525 pix firewalls then into the racks with customer supplied switches within the rack. I want to replace all the 3640 and 2950 switches with a 6500 series switch. The only routing we do within the 3640's is subnet routing to the switches which make up individual networks for each customer. My goal is to use the 6500 switch to limit bandwidth for each port feeding a customer and to eliminate all but the 7200 router and the 2950 switches. Does anyone know of a reason or reasons this would not work or if it's just a bad idea. Looking for pro's and con's,

Router For BGP 100Mbps

Mar 18, 2007

We currently have a single 100Mpbs (currently pushing ~40Mpbs) feed from a single upstream provider. Routing is handled by our transit provider.

We wish to provide a more resilient setup and are now looking to install our own BGP router(s) and take a second feed from another provider. I have a looked around the Cisco website and this forum but am unsure which model of routers / layer 3 switch we should be looking at.

A layer 3 switch looks more cost effective but doesn't appear to support enough routes for BGP without great expense. Would a 2600 router be enough or should I be looking at something higher like the 7600 series?

Router And A Firewall

Oct 31, 2007

I am about to design my company network.

The network will be designed like : we have 3 providers of IP transit, one will be the main network while the two other will feed the first network and manage a highly available network, probably using protocols like BGP4 and OSPF.

The current size of each fiber is 45 Mbit/s per operator. So I am looking for :

A router :
- able to handle each provider with up to 200 MBit/s in/output
- able to support protocol such as BGP4 or OSPF
- able to output snmp for monitoring
- have a little intuitive GUI for basic operations and have a real routing OS (like IOS or JunOS)
- is branded and warrantly (a plus would be hardware extensible)
- not too big box, something between 1 and 6U

A firewall :
- able to handle ALL the traffic to all carrier
- able to work as a SPF (drop all, allow only what I want, very accurate rules)
- have a little intuitive GUI for basic operations
- not too big box, something between 1 and 6U

About brand, most probably about Cisco, Juniper, Extreme or some good brand.

Which model would you advice me as router and which as firewall ? The price is not the main proccupation until it will do job just fine, but I would prefer to don't buy too expensive also.

The routing would be thorugh BGP with partial routes.
