hop of routes sent to a peer
or peer group.
peer
{ group-name | ip-address
[ mask-length ] }
next-hop-local

the next hop for routes sent to a
peer or peer group.
13. Configure BGP
to not
change the next hop of
routes sent to an EBGP peer
or peer group.
peer
{ group-name | ip-address
[ mask-length ] }
next-hop-invariable
By default, the router sets itself as
the next hop for routes sent to an
EBGP peer or peer group.
In an inter-AS option C network
where an RR is used to advertise
VPNv4 routes, configure this
command on the RR so the RR
does not change the next hop of
routes sent to EBGP peers and
clients.
