A fix for ID 945265 (https://cdn.f5.com/product/bugtracker/ID945265.html) introduced strict checking of a peer-id. This check might be not desired in some configurations.
BIG-IP will not pass the NLRIs between two eBGP peers. The following message can be seen in debug logs: 172.20.10.18-Outgoing [RIB] Announce Check: 0.0.0.0/0 Route Remote Router-ID is same as Remote Router-ID
EBGP peering with two routers in the same autonomous system, configured with the same peer-id.
Change peer-ids to be unique on eBGP peers.
