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

ip-address: IP address of the peer.

Use the peer label-route-capability command to enable the exchange of 
labeled routes with an IPv4 peer or peer group.

Use the undo peer label-route-capability command to disable the capability.

By default, the device does not advertise labeled routes to an IPv4 peer.

According to the networking scheme, the peer label-route-capability command 
enables the exchange of labeled IPv4 routes with:

■

ASBR PEs in the same AS.

■

PEs in the same AS.

■

the peer ASBR PE.

# Specify to exchange labeled IPv4 routes with peer 2.2.2.2.

group-name: Name of the peer group, a 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 an EBGP 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 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.
