PBR using "verify-availability" can verify next hop reachability in route-maps. You can also, as mentioned, specify a non connected next hop. This would result in a recursive lookup in the routing table. Also you can specify multiple next hops that the router can try.
Here is a URL and the command needed to do this verification process mentioned above. set ip next-hop verify-availability http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/ip_c /ipcprt2/1cdindep.htm Raza ""Chris Charlebois"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > The question is how would the router know the host is down without some sort > of heartbeat. > > My next question, and this shows my shallow knowledge of PBR, but can the > next-hop be a non-local address?
