group-name: Name of a neighbor peer group, consisting of 1 to 47 alphanumeric 
characters.

Use the peer default-route-advertise command to enable a peer (group) to 
transmit a default route.

Use the undo peer default-route-advertise command to remove the existing 
configuration.

By default, a peer (group) does not transmit a default route.

This command does not require any default route in the routing table but 
transmits a default route whose next hop address is itself to the peer 
unconditionally.

# Enable the peer group test to transmit a default route.
