Yeah, I was thinking of that issue as well. Perhaps subinterfaces could be used like int gig 0/0 ip address 69.147.218.100/24 int gig 0/0.0 ip address 206.108.255.100/24 router bgp 65500 neighbor 69.147.218.1 update-source gig0/0 neighbor 206.108.255.1 update-source gig0/0.0 but I don't have anything to test that out with right now. (not using cisco to talk to MICE right now). But I think my two bilateral peers can probably wait for a renumber at some future time as it is. > Hmm...

You've also got to duplicate ALL of your peer BGP sessions beforehand as well. Why? Well, I don't believe Cisco can initiate a BGP session on a secondary address so once a $C router switches their primary and secondary, they cannot initiate a BGP session. Not a problem yet.
