iBGP advertisement interval
Hello. Nanog I thought BGP advertisement interval is the following. ibgp : 5 second, ebgp : 30 second. But, now I realize that the default ibgp interval of Cisco is 0 second. (ios 12.0 & IOX) (it displays "Default minimum time between advertisement runs is 0 seconds") When did it change? ^^; I wonder if No interval time for bgp advertisement would bring insecure network by flapping network. Do you think I have to change the default value of interval time to longer? And I 'm curious about what the default value of Juniper router is. Because I have to implement with the Juniper and Cisco mixed.

On the 6500, this seems to have been changed somewhere in the 12.2SX line.

The answer to that probably depends on which platform/train you're interested in.

More annoying, AFAIK, JunOS has a default update time of 0 for eBGP, and I'd imagine it's the same for iBGP. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
