Hi Group
 
when testing teh bgp dampening feature, I was flapping a route by sshutting/no shutting a loopback interface, which is advertised in BGP through network commands.
 
1. When I shut the loopback interface it takes much longer time to advertise to eBGP neighbor than a iBGP. It advertises to iBGP immediately but to eBGP it takes around 10 to 15 seconds.
 
2. If I remove the network statement to cause the flap, it is even more worse. it taking around 35 to 45 seconds for the change to get advertised.
 
is this a right behavior and why?
 
Thanks
Bhaskar
