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.
To use BGP as an IGP routing protocol, issue the enable
