Router B configuration
Router B is the LDP LSP transit router and the GRE tunnel ingress router. The user needs to
configure an OSPF routing instance. Next, the user configures the loopback address, the Ethernet
interface, and then the GRE tunnel. Lastly, the user configures MPLS and enable LDP. See
Figure 50 .

Router C is the LDP LSP transit router and the GRE tunnel egress router. The user needs to
configure an OSPF routing instance. Next, the user configures the loopback address, the Ethernet
interface, and then the GRE tunnel. Lastly, the user configures MPLS and enable LDP. See
