Although you do not need to configure MPLS on the P routers in this example, it is needed on the PE routers for the interface between the PE and CE routers and on the GRE interface (gr-1/1/0.0) linking the PE routers (Router A and Router D). Configure MPLS, BGP, and OSPF on Router A:
- [edit protocols]
- mpls {
- interface all;
- }
- bgp {
-
- group pe-to-pe {
- type internal;
-
- neighbor 10.255.14.178 {
-
- family inet-vpn {
- unicast;
- }
- }
- }
- }
- ospf {
-
- area 0.0.0.0 {
- interface all;
-
- interface gr-1/1/0.0 {
- disable;
- }
- }
- }
