Configuring LDP for Signaling

Navigate to the top of the configuration hierarchy and specify the LDP protocol. Enable local interfaces that communicate with a PE router or provider router, and the loopback interface of the PE router.

(PE and provider Services Routers)

(See the interface naming conventions in the J-series Services Router Basic LAN and WAN Access Configuration Guide.)

1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
2. Next to Ldp, click Configure or Edit.
3. Next to Interface, click Configure or Edit.
4. In the Interface name column, type interface-name.
5. Click OK.
6. Repeat Steps 4 and 5 for each interface you want to enable.

From the [edit] hierarchy level, enter the following command for each interface you want to enable:

edit protocols ldp interface interface-name

Configure OSPF for each interface that uses LDP.

For OSPF, you must configure at least one area on at least one of the router's interfaces. An AS can be divided into multiple areas. This example uses the backbone area 0.0.0.0.

(PE and provider Services Routers)

For OSPF:

1. On the main Configuration page next to Protocols, click Configure or Edit.
2. Next to Ospf, click Configure or Edit.
3. For Layer 2 VPN or circuit, select Traffic engineering.
4. Next to Area group, click Add new entry and add the area.
5. Next to Area group, select the area (0.0.0.0).
6. Next to Interface group, select Add new entry.
7. In the Interface name box, type interface-name.
8. Click OK.
9. Repeat Steps 5 through 7 to enable additional interfaces.
10. Click OK twice to return to the Protocols page.

For OSPF:

1. From the [edit] hierarchy level, enter the following command for each interface you want to enable:

   edit protocols ospf area 0.0.0.0 interface interface-name

2. For Layer 2 VPN or circuit, move up to the [edit protocols ospf] level and enter

   set traffic-engineering
