Your router can not reach the address that is specified in the LSA (I can
tell this from the routing table :-)). Try pinging 182.18.2.1. Since it is
not reachable the LSA will not be placed in your routing table.
Fix the routing issue with the 182.18.2.0/24 network and our LSA will
appear.
Take care,
Paul Borghese
