Like other Layer 2 VPNs, you must enable a VPLS instance to isolate VPLS traffic from other network traffic. An important element of a VPLS instance is the signaling protocol. You can configure BGP signaling, LDP signaling, or both BGP and LDP signaling in a VPLS instance.
To configure LDP signaling, you must first enable a VPLS instance to isolate VPLS traffic from other network traffic. To configure, include the instance-type vpls statement at the [edit routing-instances instance-name] hierarchy level. To configure LDP signaling within the instance, identify the virtual circuit with the vpls-id statement and specify the PE routers participating in the instance with the neighbor statement:
- [edit]
- routing-instances {
-
- instance-name {
- instance-type vpls;
- interface ge-0/1/0.0;
-
- protocols {
-
- vpls {
- vpls-id id-name;
- neighbor neighbor-id; # The neighbor-id should be the loopback address of # the remote
PE router.
- }
- }
- }
- }
To fully enable LDP signaling on a PE in a VPLS instance, you must also enable ldp on the loopback interface of the router. To configure, include the interface lo0.0 statement at the [edit protocols ldp] hierarchy level:
For LDP signaling within a VPLS routing instance, the JUNOS Software supports the following values only:
