RE: Eigrp filtering

Hi,

If you do not need redundancy, you can use distribute-list with ext.ACL.
In distribute lists, the source of the ACL is the router sending the route
and the dest. is the route itself.
If you want to limit ACL to certain interfaces you can also add the
interface with its direction (in/out) to the distribute-list command.

router eigrp 1
  distribute-list 100 in serial0

access-list 100 permit ip host <R1> host <Route1>
access-list 100 permit ip host <R2> host <Route1>
access-list 100 deny ip any host <Route1>
access-list 100 permit ip any any

Kubilay.

No redundancy per say...
Maybe route 1 can be accepted from only 1 router (but two or more tunnels)
or from a few routers but nowhere else (the no where else is the most
important part of the equation)
