Hi,
This is basically a call center setup where all external voice connections will get terminated into edge switches.
We need to run iBGP between ASA5540-AIPSSM, 6500 switch having FWSM modules.
eBGP will run b/w ISP & the Internet Routers, rest will be on iBGP.
Can someone help with a sample config for achievening the same??

Dear acharyar123,
Please find the below configuration that you can do for both of your internet routers.
router BGP ASN
no synchronization
no auto-summary
bgp log-neighbor-changes
neighbor x.x.x.x remote-as ASN
neighbor x.x.x.x description SIFY_RF_PEERING
neighbor x.x.x.x update-source x.x.x.x neighbor x.x.x.x version 4
neighbor x.x.x.x default-metric 200 #MED#
neighbor x.x.x.x prefix-list zz out
neighbor x.x.x.x prefix-list zz in
neighbor y.y.y.y remote-as ASN
neighbor y.y.y.y description for ibgp
neighbor y.y.y.y version 4
neighbor y.y.y.y update-source t.t.t.t #LAN#
Network 202.x.x.x 255.255.255.248
Network 210.x.x.x 255.255.255.0
Network 210.x.x.x 255.255.255.252
Network 221.x.x.x 255.255.255.240
Network 221.x.x.x 255.255.255.240
Network 221.x.x.x 255.255.255.248
Network 192.192.16.0 255.255.255.240 # LAN#
ip prefix-list zz deny LAN
ip prefix-list zz permit 0.0.0.0/0 le 32
ip prefix-list zz permit 0.0.0.0/0 le 32
ip route 0.0.0.0 0.0.0.0 x.x.x.x
Also to track for redundency you can use SLA Tracking:-
standby 1 track 22 decrement 12
Ip sla 11
Icmp-echo < to the Primary interface to which tracking is done> source-interface Gi0/0
frequency 5
ip sla schedule 11 start-time now life forever
Track 22 rtr 11 reachability
also before you configure IP Sla configure HSRP on the ethernet /gig interface.
Please let me know if you require any more thing
Thanks and Regards
