Link Status and the IP Forwarding
If the Frame Relay link is down, the address will automatically be removed from the routing table. If there are
any routes which specify this IP address as the next-hop, the routing table will show the state of
noPath(3)
(see
figure 134).
Figure 134. Link status and IP forwarding
When the Frame Relay Link returns to the UP state, the IP route for the link will be re-added and used to for-
ward IP packets. Any routes that specify this IP address as the next-hop will automatically return to the active
state.
