Yes,
My understanding is that you don't want routes coming from r3 via r2 to
r1 to be passed back to r3, and also routes coming from r1 via r2 to r3
should never be passed back to r1.
Ok, you can filter these via subnet, but why? That's the hard way.
Both eigrp and ospf support route tagging. Just tag the route the first
time it transverses r2, and block it from reentering r2.
You can find examples of redistribution route tagging in the archives.

Subject: Just for a confirmation !! on redistribution
Morning Guys !!
Is my way of redistribution correct please confirmed after reading this
:
r1------(eigrp)-------r2------(ospf)-------r3
r1 running eigrp
r2 running eigrp and ospf
r3 running ospf
r1 have routes 1,2,3
r3 have routes 4,5,6,7,8,9,10,11,12,13,14,15 (lots of routes)
on r2 i will redistribute and be specific that no route loop is formed
so i
use route-map in redistribution.
i made a route-map on r2 which only calls eigrp routes
route-map eigrp
match ip address 1
access-list 1 permit 1
access-list 1 permit 2
access-list 1 permit 3
for ospf i dont make access-list but instead i denied 1,2,3 and allow
others ,
like :
route-map ospf deny 10
match ip address 1
route-map ospf permit 20
ospf route-map is calling that same access-list that is made for eigrp
but
here this access-list is denied and rest are permitted.
Is this the correct way or i should make an access-list for ospf and
call
4,5,6,7,8,9,10,11,12,13,14,15 (takes lot of time) and apply it to the
ospf
route-map.
Just want to make sure .....
waiting for comments.
