Gaurav,
For the first email you sent out, you would want to use metric to do route
filtering when you are dealing with prefixes from routers running the same
protocol. In other words, you use the distance command to influence prefixes
from getting into the routing table when you are dealing with sources
running different routing protocols.
As for the second email, I think its the approach that is abit not spot on.
OSPF usues LSAs, remember and I am not sure you can achieve what you are
trying to do with distribute lists. With OSPF. a distribute list (as I
remember, you would have to check this) would only prevent the prefix from
making it to the routing table and NOT the LSA from being learnt! TO filter
the LSA from being learnt, you need a filter-list tool.
Anyways, HTH,
Sadiq
