After a jug of coffee I tried being a bit more methodical.
I took the entire network down and brought up one router at a time.
I monitored the prefix 192.168.30.0/24 from a route-collector sitting on
192.168.30.10,
the first router brought online was ar213-FRA which has 192.168.30.0/24 as
connected.
Have a look at originator_id in the different steps.
bgpd config at the bottom of the file.
I am running a current a few days old with Hennings next-hop self patch.
Highlights, step 2 & 3 shows backward originator_id, step 4 shows changed
originator_id.
Please let me know if there is any other info I can provide.
1. Bring ar213-FRA online
