ok if you do this aren't you defeating the whole purpose of the summary?

I think the idea is to pass the summary but not have it point to Null 0

Hi Luke,
        From my experience it's quite simple

access-l 1 deny 172.16.0.0 0.0.0.0
access-l 1 permit any
router eigrp 10
distribute-list 1 in null0
That usually works for me, let me know how you go.
Regards,
        Lachlan

Ok,

Here is a scenario that a friend told me about and I just don't get... maybe
I lack the right amount of brain cells so forgive me =)

tokyo ------- ether0 -----------------ether 0 ------------------ sydney

tokyo is running EIGRP with about 4 loopbacks 172.16.1.0, 172.16.2.0,
172.3.0, 172.4.0

Sydney is running OSPF and EIGRP. I was told to allow 172.16.0.0 ( a
summary net) into OSPF without the routing procotols generating a route to
Null 0.

Ok, so I do a summary for eigrp on interface ether 0 in Tokyo. Do a show ip
route and I see 172.16.0.0 pointing to null 0 (as it should).
How do I get rid of the null 0? I don't think this is possible.

Could someone shed some light into this? This is crazy...

Luke
