It seems that we had a similar issue at CNS that James Stahr mentions below. We removed the old addresses last week without bouncing the BGP sessions and the old addresses were still in use (we had the new addresses in our routers for several weeks but they apparently weren't being used.) Caused a few problems till we reset BGP. All is good now.

But it looks like I did the swap too quickly and even though 69.147.218.26 was now a secondary address and all of my BGP sessions were using 206.108.255.26 as the source IP, I was still advertising the next-hop using the old block. Turns out if the BGP sessions don't drop, the next-hop won't change. As I've previously stated, my $C equipment cannot advertise routes with BOTH next-hops. >> >> -James >> >> >> -----Original Message----- >> From: David Farmer [mailto:[log in to unmask]] >> Sent: Sunday, December 16, 2012 7:46 PM >> To: MICE Discuss; [log in to unmask]; James Stahr; [log in to unmask]; [log in to unmask] >> Cc: [log in to unmask] >> Subject: MICE Renumbering >> >> OK, I think it is now time for a little public shaming; the following MICE participants are only announcing their prefixes using the old next-hop addresses through the route servers.
