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. Dean Bahls CNS Sent from my iPad On Dec 16, 2012, at 8:22 PM, David Farmer <farmer@UMN.EDU> wrote:
I apologize for implying you hadn't done you part and thanks for fixing it, I now see you announcing the new next-hop address.

I can't speak for anyone else, but I thought I had completed the changes by swapping my $C secondary addresses around a few weeks ago and thought I was done. 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.

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. We were all suppose to be using only the new addresses as of two weeks ago. There is one other participant announce with both the old and the new next-hop address, we (Northern Lights GigAPOP) just stopped doing this earlier today, and are now announcing using only the new next-hop addresses. All other participants are announcing to the route servers are using only the new next-hop addresses.

Please convert your peering session to announcing with the new next-hop addresses, ASAP. If for some reason you can't do this in the next week, please send a note to the MICE-DISCUSS mailing list detailing when you will be converting.
As a reminder, here is the original cutover schedule that was emailed out several months ago:
Addition of Address Secondary: before 10/1/2012 New Prefix Announcements: after 10/1/2012 Final use of old IP address next-hop: before 11/30/2012 Removal of old IP address range: after 12/1/2012 Project End: 12/31/2012
