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.
