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.
