Configuring Static Unicast Routes for Point-to-Multipoint LSPs

You can configure a static unicast IP route with a point-to-multipoint LSP as the next hop. For more information on point-to-multipoint LSPs, see Point-to-Multipoint LSPs, Point-to-Multipoint LSP Configuration Guidelines, and Configuring CCC Switching for Point-to-Multipoint LSPs.

To configure a static unicast route for a point-to-multipoint LSP, complete the following steps:

1. On the ingress PE router, configure a static IP unicast route with the point-to-multipoint LSP name as the next hop by including the p2mp-lsp-next-hop statement:

   p2mp-lsp-next-hop point-to-multipoint-lsp-next-hop;

   You can include this statement at the following hierarchy levels:

   • [edit routing-options static route route-name]
   • [edit logical-systems logical-system-name routing-options static route route-name]
2. On the egress PE router, configure a static IP unicast route with the same destination address configured in Step 1 (the address configured at the [edit routing-options static route] hierarchy level) by including the next-hop statement:

   next-hop address;

   You can include this statement at the following hierarchy levels:

   • [edit logical-systems logical-system-name routing-options static route route-name]
   • [edit routing-options static route route-name]

   Note: CCC and static routes cannot use the same point-to-multipoint LSP.

For more information on static routes, see the JUNOS Routing Protocols Configuration Guide.

The following show route command output displays a unicast static route pointing to a point-to-multipoint LSP on the ingress PE router where the LSP has two branch next hops:
