set ip next-hop verify-availability posted 09/15/2006

Hi,

there is a question Task 4.6 Lab6 in the IE Workbook, asking for reachability to neighbors and set the
"default-information originate subnet always" route an the availability to these routers.


The Solution guids provides checking with a route-map for routes to both in the local routing table.
But is there another solution for this. I felt like checking availability by icmp ping to these routers
with "set ip next-hop verify-availability" and then withdraw or set the default route. But there is no
Match clause for test rechability.
set ip next-hop verify-availability is only to set a next hop, if the next-hop is available. So the route-map
won't count.
