The LSR assigns a label to each route. The local direct route is assigned a POP. Path Protection: 2 Common Link(s), 2 Common Node(s) AutoRoute: enabled auto-bw: disabled If the link flaps, the LDP session will be re-established, and the label bundle must be exchanged again . It is very inefficient to rebuild the LDP session. We can protect the session and implement LDP session between the two directly connected LSRs . After the protection,cisco exam site, a destination-based LDP session is established between the two LSRs , that is, the target LDP session . When the direct link between the two LSRs is DOWN , as long as there exists between the two LSRs .
