allocate-label
Use this command to allocate MPLS labels to all/route-map permitted IPv4 prefixes present in the BGP RIB. This command enables the label allocation to IPv4 prefixes, where labeled unicast (LU) routes can be exchanged with IPv4 Peers having BGP labeled-unicast capability. This command allocates labels for all IPv4 unicast prefixes (afi:1, safi:1) and IPv4 labeled-unicast prefixes (afi:1, safi:4).
Once configured, BGP will allocate labels to IPv4 unicast prefixes after the expiry of current BGP RIB scan time (default: 60 seconds).
Use the no form of this command to release the labels and disable BGP from allocating label to IPv4 prefixes.
