12.1 LDP configuration
LDP is a tag distribution protocol. To find the neighbors hello messages are sent to the multicast address
224.0.0.2. When exchanging hello messages, routers learn each other's transport addresses. A router with a
bigger address initializes the TCP session. After checking the parameters, the LDP session is considered
established.
ESR routers support the following LDP operation modes:
Tag information exchange mode — Downstream Unsolicited;
Mechanism for controlling the distribution of tags — Independent Label Distribution Control;
Label retention mode — Liberal Label Retention;
On interfaces where LDP and MPLS switching are enabled, the firewall must be disabled.

The current version LDP only works with IPv4 addresses.
