Router D configuration
Router D is the LDP LSP egress router. The user needs to configure an OSPF routing instance. Next,
The user configures the loopback address, the Ethernet interface, and then the MPLS tunnel with
LDP enabled. See
Figure 50 .

Deleting a GRE tunnel configuration
A GRE tunnel configured as an MPLS interface cannot be directly deleted. First, the user must
delete the GRE tunnel from the mpls-interface configuration, and then the user can delete the GRE
tunnel.
Viewing MPLS over GRE information and statistics
The user can view configuration information and various statistics about MPLS over GRE.
The user can view the tunnel interface administrative and operational state by entering the show
mpls interface tunnel command.
