To do an LDP Configuration Example , we will use the below basic topology. Here, we will configure these two routers to become an LDP peer and establish an LSP session.
Configuration on Router B
Here, I would like to inform you about an important point. LDP sessions established between “transport addresses” of the routers. In Nokia Service Routers, this transport addresses are “system addresses”. The session is established between these system addresses. So, before LDP neighbour discovery, system addresses must be configured.
