multicast | l2vpn vpls-vpws | vpnv4 unicast | vpnv6 unicast
}
Step 7
Example:
RP/0/RSP0/CPU0:router(config-bgp)#address-family ipv4
unicast
Configures receive capability of multiple paths for
a prefix to the capable peers.
additional-paths receive
Example:
RP/0/RSP0/CPU0:router(config-bgp-af)#additional-paths
receive
Step 8
Configures send capability of multiple paths for a
prefix to the capable peers .
additional-paths send
Example:
RP/0/RSP0/CPU0:router(config-bgp-af)#additional-paths
send
Step 9
Configures additional paths selection capability for
a prefix.
