Speaking as someone who soaks in how some customers use BMP, the per-AFI/SAFI end of rib is a feature rather than a bug. BMP already serves to push the firehose of a router down a drinking straw. Being able to tell you're done with one address family is helpful to let some things come to convergence rather than waiting on everything. The other headache of the single "I'm done" bit is the consequence on trying to get all of the per-AFI/SAFI queues to be done at the same time. For example: IPv4 unicast is done, no EoR is sent. IPv6 unicast starts doing its work. IPv4 unicast has more churn go through IPv6 unicast is done, no EoR is sent. System needs to go back to trying to get IPv4 unicast done to send EoR. Pray that nothing else changes... -- Jeff
