Cisco Policy-based routing question

[Cooky]

Say, a route-map is used to specify the next-hop. What happens if the next-hop router goes down??
What would the router that has the route-map do in that case? Would it
a.route traffic to null0 interface
b.drop packets / deny traffic
c.default to one of the dynamic routing protocols enabled on that router
or d. none of the above?

my guess is drop.

I forget the order, but since the route-map matches it is processed (regardless if the next hop is down). No layer 2 address for next hop means packet cannot be forwarded, no layer2 address can be formed on the packet.

drop.

I may be wrong...

"The set ip next-hop command verifies the existence of the next hop specified, and?

if the next hop exists in the routing table, then the command policy routes the packet to the next hop.

if the next hop does not exist in the routing table, the command uses the normal routing table to forward the packet.

"

But that says if next-hop isn't in routing table, normally you would use a next-hop that is on the same network as one of the router interfaces, hence a route (directly connected interface) to the next hop would always be in the table.

Thank you.
