Usage Information If you configure the neighbor maximum-prefix command and the neighbor receives more prefixes than the
neighbor maximum-prefix command configuration allows, the neighbor goes down and the show ip bgp
summary command displays (prfxd) in the State/PfxRcd column for that neighbor. The neighbor remains down
until you enter the clear ip bgp command for the neighbor or the peer group to which the neighbor belongs
or you enter the neighbor shutdown and neighbor no shutdown commands.

hop-self [all] command.

Usage Information
If you configure the set next-hop command in ROUTE-MAP mode, the configuration takes precedence over
the neighbor next-hop-self command.
If you do not use the all keyword, the next hop of only eBGP-learned routes is updated by the route reflector. If
you use the all keyword, the next hop of both eBGP- and iBGP-learned routes are updated by the route
reflector.
