OSPF neighbors on 2800

Unanswered Question
Nov 4th, 2009

i have about 900 router connected to two service provider with the Data center using L2 MPLS ATOM. i need to know the 2800 capability with about 900 neighbor and 4000 routes. if it works fine how can i tune the network to get high speed convergence and minimize the routing update.

I have this problem too.

Hello Mohamed,

I would be satisfied to have a C2800 that has 900 neighbors and 4000 routes!

have you been able to have 900 neighbors on it, who is the DR?

be aware that any tuning would imply a greater use of cpu resources.

For example using sub-second hello timers with 900 neighbors is a problem.

Hope to help

Hi Giuseppe

i do not implement it now but i compare between the RIP and OSPF. if you have any document related to ospf and 2800 please send it to me as i think it will cause high CPU and Memory utilization.
