IP monitoring with interface as next-hop option

IP monitoring enables you to configure a static route with a P2P interface as a next-hop action when IP monitoring has failed.

The following added functions support the track-ip option:

• Next-hop type checking: IP address or interface.
• Interface type checking for next-hop. Only a P2P interface is supported; an error message results when the configuration is committed.
• You can use the interface as a next-hop to construct route parameters and call RPD API to add a static route; log route addition results.
• You can use existing code to delete the route when the primary route recovers.
