group-name: Name of the peer group, a case-sensitive string of 1 to 47 characters. 

ip-address: IP address of the peer. 

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. 

Related commands: peer ebgp-max-hop in BGP Commands of the IP Routing Volume. 

# In BGP-VPNv4 subaddress family view, configure the device not to change the next hop of a route 

when advertising it to EBGP peer 1.1.1.1.
