Does the Cisco 3600 Series Router Support Full BGP?

If it supports a full Border Gateway Protocol (BGP) route table and multiple neighbors, what is the recommended amount of memory?

Re: Does the Cisco 3600 Series Router Support Full BGP?

Yes it does but you'll need to figure out the number of

expected routes to calculate the required memory

but a full memory capacity of the c3600 should be able to support BGP.

example of how to calculate your mem requirement for bgp.

say you have 100000 bgp routes coming from only

one neighbour. then the calculation is as below.

(a) number of prefixes (240 bytes per prefix)

(b) number of routes (240 bytes per route)

(c) number of alternate paths (110 bytes per alternate path)

BGP table : 100000 X 240 =24MB

routing table (bgp) 100000 X 240 =24MB

Alt. Paths : 100000 X 110 X N (n=0)=0

total memory requirement = 48MB/s. for 100000 bgp routes
