MikroTik RouterOS implements Label Distribution Protocol (RFC 3036, RFC 5036) for IPv4. LDP is a protocol defined for distributing labels. It is the set of procedures and messages by which Label Switched Routers (LSRs) establish Label Switched Paths (LSPs) through a network by mapping network-layer routing information directly to data-link layer switched paths.
Max path vector limit used for loop detection. Works in combination with loop-detect property.
transport-address (IP; Default: 0.0.0.0)
Specifies LDP session connections origin address and also advertise this address as transport address to LDP neighbors. If set to 0.0.0.0 highest IP address on the router is used.
use-explicit-null (yes | no>; Default: no)
Whether to distribute explicit-null label bindings.
