Say I have 4 x ccr1036 router A, B, C, D.
Each router has a ISP BGP connection and each routers has a connection to VLAN Internet.
eBGP to ISP and iBGP over Internet.
On the internet vlan I have a fw it routers via DGW. the DGW is handled by the routers using a VRRP on the Internet vlan.
lets say C has the VRRP now.
lets say my example prefix i'm looking at i 126.96.36.199/24 and it routes via router A.
If I disable the BGP peer on router A. My advertised prefixes are removed from router A, ISP route table and slowly inbound filters down.
But the ASA -> VRRP via router C, which sends it to router A, router A no longer has the route and sends it to router B,C,D which in turns sends it back to router A.
So the loop begins.
It seems to take 3 min to get tge BGP to converge between router A and B,C,D.
Is there some way to make this quicker ?
