Configuring RSVP and OSPF for LMP Peer Interfaces

After you have configured the LMP peers as described in Configuring LMP Peers, add the peer interfaces to RSVP and OSPF. The peer interface name must match the peer name configured in LMP. Once the peer interfaces are added to the protocols, the traffic engineering link local and remote addresses can be signaled and advertised to peers like any other interface enabled for RSVP and OSPF. These addresses act as virtual interfaces for GMPLS.

Note: When adding the virtual peer interfaces to RSVP and OSPF, do not configure the corresponding physical control channel interface in either protocol. If you include the interface all statement, you must disable RSVP and OSPF protocols manually on the control channel interface.

To configure peer interfaces in RSVP and OSPF, complete the procedures in the following sections:

Configuring RSVP Signaling for LMP Peer Interfaces

To configure RSVP signaling for LMP peers, configure the LMP peer interface by including the peer-interface statement at the [edit protocols rsvp] hierarchy level:

[edit protocols rsvp]peer-interface peer-interface-name {(aggregate | no-aggregate);authentication-key key;disable;hello-interval seconds;(reliable | no-reliable);}

The statements configured at the [edit protocols rsvp peer-interface peer-interface-name] hierarchy level have the same functionality as the statements configured at the [edit protocols rsvp interface interface-name] hierarchy level.

Configuring OSPF Routing for LMP Peer Interfaces

To configure OSPF routing for LMP peers, configure the name of the LMP peer by including the peer-interface statement at the [edit protocols ospf area area-number] hierarchy level:

[edit protocols ospf area area-number]peer-interface peer-interface-name {dead-interval seconds;disable;hello-interval seconds;retransmit-interval seconds;transit-delay seconds;}

For information about how to configure OSPF statements, see the Junos OS Routing Protocols Configuration Guide.

Configuring the Hello Interval for LMP Peer Interfaces

Hello packets are used to indicate to neighboring routers that the peer interface is still up and running. The hello interval must be the same for all routers on a shared logical IP network. You can specify a hello interval from 1 through 255 seconds. The default hello interval is normally 10 seconds. For nonbroadcast networks, the default hello interval is 120 seconds.

To specify how often the router sends hello packets out the peer interface, configure the hello-interval statement:

You can configure this statement at the following hierarchy levels:

  • [edit protocols ospf area area-number peer-interface peer-interface-name]
  • [edit logical-systems logical-system-name protocols ospf area area-number peer-interface peer-interface-name]
