peer next-hop-invariable (BGP-VPNv4 subaddress family view)

Description
Use the peer next-hop-invariable command to configure the device not to change the next hop of a route
when advertising it to a peer.
Use the undo peer next-hop-invariable command to restore the default.
By default, a device uses its address as the next hop when advertising a route to its EBGP peer. In the
inter-provider option C application, you need to configure next-hop-invariable on the RR for multi-hop
EBGP neighbors and reflector clients to ensure that the next hop of a VPN route will not be changed.
