Viewing IPv4 Label in BGP Routes
The labeled BGP IPv4 (RFC 3107) enables BGP to distribute MPLS label along the routes it advertises. 
The label mapping information for a particular route is added in the same BGP update message that is 
used to distribute the route itself. The label mapping information is carried as a part of the Network Layer 
Reachability Information (NLRI) in the...
