Usage Information If you configure the neighbor maximum-prefix command and the neighbor receives more prefixes than
allowed by the neighbor maximum-prefix command configuration, 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.

Usage Information
If you configure the set ipv6 next-hop command in ROUTE-MAP mode, its 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.
