Memory to run BGP with a 2611xm platform

I'am waiting on some new 38xx hardware in the meantime I need to bring a few sites up with some existing 2611xm's. I was told they may need extra memory. We are peering with our mpls provider using BGP.

Anyone else using the 2611xm's running bgp?

Re: Memory to run BGP with a 2611xm platform

It all depends upon the number of routes that you are expecting your router to hold. If it is the full Internet routing table (at around 220k) then you would need around 256Meg, if your only looking at around 300 routes then the memory requirement is going to be a lot less a few meg. It also depends on whether the router is running CEF (which I don't know if it is supported or not) again this will increase the amount of memory required.

You could simply load up the 2611 with the routes and see what happens, if it looks like the router is getting overloaded, then you could put a filter list in to restrict the numbers of routes that are learned to those that you need access to.


Happy Christmas :)
