Version Description
7.8.1.0 Introduced on the S-Series.
7.7.1.0 Introduced on the C-Series.
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.
