anyone know a good site for used ciscos and routers that support BGP ?

and you give me some model numbers and pricing that support such protocol...

Most of them can. But, it depends on the version of IOS.

If you're willing to consider other brands of routers, check out http://www.imagestream-is.com/ they are pretty affordable.

I think uuallan has used their routers before.

Depends on what type of connection you are going to use. What are you looking to route?

Depending on what you do, you will need plenty of memory. At this point and time a full routing table contains about 108k entries and as it grows it sucks up memory. Let us know what you are trying to do and we can help you out. It actually isn't as hard as it looks, but don't tell anyone (job security)... :stickout

Well talking with HE (our dc) they have been talking to us about redunancy and said it can be easily done with a router with bgp support and a ?AS Number?

Bascially they would bring in a line from their san jose dc directly into our cabniet so that if fremont's line fails, the san jose line will pick up the traffic

I would be interested in any reliable routers that can do the job :)

AS Number is an autonomous system number which if I recall correctly is a number number that is associate to a line/pipe. So maybe PipeA has an AS number of 23 and PipeB has an AS number of 42.

I think I am correct but haven't done any CISCO since passing my CCNA a couple of months ago.

I'm not sure on the specifics of what router you would need to be looking at but I would assume a few steps above your budget 1600 series. Mind you, I don't know much about BGP. I think your looking at well over a few thousand $ for something good.

Really, it depends on how much traffic you are looking to move through it. What type of connection?

Hi,

I'm looking to put together 3 partial-t3s

like 3 10 meg lines together for BGP whats the best hardware solutuion?

Anybody here have an AS from arin? they cost around $3k a year right?

AS costs $500 first year, $30 for each year after.

ebay!

traffic, at the moment, we push 6 mbps.....what else would u need to know

Basically Im just looking for model numbers, pricing etc...somewhere to get started.

If your provider is talking about bringing in a second line from another DC for you, your going to be running EIGRP, (or in other words, internal BGP for non cisco, with a internal AS number)

If you are talking about bringin in a second provider with a different AS number themsleves (rather than 2 lines, each from the same provider) then you are going to need to talk to ARIN.

We currently maintain an ARIN block for our US operations, and several RIPE blocks for Europe, with your own AS number you can then take BGP feeds from providers and announce your routes on the internet (rather than asking your single provider to announce you, you have a huge amount more control)

If your running a full BGP feed your going to need a Cisco 7200 minimum, with 256mb dram, and 32mb flash; if you are running a partial feed, you can probably get away with a 2600 at a push.

There are of course other options, Juniper kit is considered fantastic by those who use it, but Cisco is almost the de facto standard.

You can pickup a second hand 7206 on Ebay for a few thousand, you'll need to check how your providers are terminating the lines, DS3/T3 cards are expensive, if you can push for ethernet termination it will push your costs down, but decrease on error checking and make troubleshooting harder.

I would agree with what has been recommended with the exception of the 2600, I don't think that would even handle a partial feed very well. There are several ways to accomplish what you have mentioned, but some of the information that has been given is not complete about the AS numbers. Each large ISP or backbone provider has an AS, if you will be running bgp with multiple providers, you will also need to get an AS. You can get these from www.arin.net, but they are not free and there are requirements and guidelines that you need to abide by. If you need additional information, let me know.

Let's not forget about the 3660 :)

When your provider talks about an Autonomous System Number they're talking about your own block of IP's. You'll need to get them from ARIN at arin.org. They are not talking about IGRP or EIGRP Autonomous System Numbers. It's a completely seperate thing.

As far as BGP goes... The routing table you would need to hold is huge. You're going to need a router with a little meat on it's bones... I wouldn't suggest anything less than a 3620 (Cisco). I'm currently using a 3660 which is pretty much the same thing, just with more slots.

I would also suggest that you find someone to set it up and manage it for you. A BGP table is not something to be messed with by someone who doesn't know what an ASN is. (no offense) There are certain rules you have to follow when running BGP and if you don't get it right they can revoke that privilage.

Good luck.
