Configuring Interoperation with Legacy Frame Relay Layer 2 Services

To configure the router to interoperate with a router that uses the legacy Frame Relay pseudowire type for layer 2 services over MPLS:

1. Configure the Frame Relay interface.
   host1(config)#interface serial 4/1:1/1host1(config-if)#encapsulation frame-relay ietfhost1(config-if)#frame-relay intf-type dtehost1(config-if)#frame-relay lmi-type ansihost1(config-if)#interface serial 4/1:1/1.1host1(config-subif)#frame-relay interface-dlci 17 ietf
2. Specify MPLS tunneling by using the appropriate command.
   host1(config-if)#mpls-relay 10.10.100.2 45 relay-format frame-relay

   or

   host1(config-if)#route interface tunnel mpls:tunnel6 45 relay-format frame-relay
3. Configure Frame Relay and MPLS on the remote PE router.
