LDP Support
  
  
        The Label Distribution Protocol (LDP) is a protocol defined by the
            IETF for the purpose of establishing 
MPLS LSPs. Using LDP,
            peer LSRs exchange label binding information to create LSPs. The LDP features supported
            in this release include:
                - Downstream unsolicited label advertisement.
 
                - Liberal label retention.
 
                - Ordered control mode.
 
                - Advertisement of labels for direct interfaces,
                        RIP routes, and static routes.
 
                - Ability to use multiple IGP routing protocols (for example
                    IS-IS, OSPF, and BGP). 
 
                - LDP loop detection.
 
                - Configurable LDP timers.
 
            
         
        
Note   
To use BGP as an IGP routing protocol, issue the 
enable
                mpls ldp bgp-routes command.
