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, see JUNOSe Command Reference Guide, About This 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
