Hi All,
We have a couple of 6500 series switches and have 3 BGP peerings to each. The 6500 series switches are loaded with WS-SUP720-3B Supervisor Engine. I believe there is a limit to the number of IPv4 routes WS-SUP720-3B supports(256,000). We also have "soft-reconfiguration inbound" configured on the BGP peerings. Thus when I do a "show ip bgp A.B.C.D" it displays three routes from 3 BGP peers and it displays an additional 3 "received-only routes" which I think is due to the "soft-reconfiguration inbound" configuration. We currently filter inbound routes from the BGP peers to be between /0 and /27
We are now looking to add another 2 BGP peerings. I am not too sure if the WS-SUP720-3B will be able to handle all the BGP routes. Is this limit of 256,000 IPv4 routes due to Processor memory limitation or is it software related? Would removing the "soft-reconfiguration inbound" save me some memory ?
Any help on this topic would be much appreciated.
Regards,
Nilesh
