Re: [c-nsp] full routes / backup router
We have a Customer with a 45-60 Mbps Constant Throughput from the internet on a 100Mbps link on a 2851 with 1GB of ram for the full Internet Routes + about 2K internal Routes. We have one of these per each(2) ISP connection.

Re: [c-nsp] full routes / backup router
Thanks Gert, Joseph and Jorge. We need to pass the full routing table to a customer who is load balancing between us and another upstream provider. As far as data throughput goes, yes, the 2911 looks like a good fit. But I was concerned about whether the CPU would be able to handle the frequent BGP updates associated with a full routing table. The routerperformance.pdf unfortunately does not list the process switching specs on the 2900's. The 2911 would be a cold spare, to be used only when the 7204VXR dies.

OTOH, why bother with BGP full tables if all you have is a single peer. gert ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
Re: [c-nsp] full routes / backup router
A 2900 would cope fine with this, for sure. Just for kicks I ran a full BGP feed to an 1841 one day a few years back and after the initial onslaught of populating the routing table it coped fine with the incremental BGP updates coming in after that. Not that I would ever recommend it but Reuben On 10/12/2010 4:07 AM, Adam Greene wrote: Thanks Gert, Joseph and Jorge.

Just a default route would work for all transit. ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
