Displaying Available Routes for Reverse-Path Forwarding

Use the show ip rpf-route command to display all available routes, only the routes to a particular destination, or routes associated with a specific unicast protocol that the router can use for Reverse-Path Forwarding (RPF).

show ip rpf-route

Use to display routes that the router can use for RPF.
Specify the IP address and the network mask to view routes to a particular destination.
Specify a unicast routing protocol to view routes associated with that protocol.
Field descriptions
- Prefix—Value of the logical AND of the IP address of the destination network and the subnet address
- Length—Length of the subnet mask in bits
- Type—Protocol type for the interface
  - Connect—Subnet directly connected to the interface
  - Static—Static route
  - protocol-name—Route learned through the named protocol
- Next Hop—IP address of the next hop for this route
- Dist—Distance configured for this route
- Met—Learned or configured cost associated with this route
- Intf—Type of interface and interface specifier for the next hop. For details about interface types and specifiers, seeInterface Types and Specifiers in JunosE Command Reference Guide.

Example 1

host1#show ip rpf-route
Protocol/Route type codes:
  I1- ISIS level 1, I2- ISIS level2,
  I- route type intra, IA- route type inter, E- route type external,
  i- metric type internal, e- metric type external,
  O- OSPF, E1- external type 1, E2- external type2,
  N1- NSSA external type1, N2- NSSA external type2
  L- MPLS label, V- VR/VRF, *- indirect next-hop
