# Defining Static Routes for Reverse-Path Forwarding

Use the ip rpf-route command to define reverse-path forwarding (RPF) to verify that a router receives a multicast packet on the correct incoming interface.

ip rpf-route

- Use to customize static routes that the router may use for RPF.
- Specify the IP address and subnet mask of the destination network.
- Specify either a next-hop IP address or an interface type and specifier, such as atm 3/0. For details about interface types and specifiers, see Interface Types and Specifiers in JunosE Command Reference Guide.
- Optionally, specify the distance (number of hops) to the next-hop address.
- Optionally, specify a route's tag number to identify a particular route in the routing table.
- Example
  host1(config)#ip rpf-route 11.1.0.0 255.255.0.0 atm4/1.1 56 tag 25093
- Use the no version to remove the static route.
- See ip rpf-route.
