configure eigrp between router 2 and 3

hjor

networker, do you mean like this:

on router 2

---

router ospf 1
redistribute eigrp 100
end

---

and 0.0.0.0 masks

If you want the ospf routes in eigrp and the eigrp routes in ospf you need to redistribute both. You would also want to use the subnets key word to ensure the subnets are redistributed.

router ospf 1
redistribute eigrp 100 subnets
end

Also when you redistribute ospf into eigrp you need to add a metric.

router eigrp 100
redistribute ospf 1 metric 10000 100 255 1 1500
end



The 0.0.0.0 mask is a personal preference and not something you need to make it work.

I was going to say that I forgot to say that I redistributed the static default route
on router 2 by typing default-information originate. I propagated the gateway of last resort to the other routers in the OSPF domain. But maybe that wasn't enough, in this wholeness. I try what you said. Thanks!

networker050184

That static route is know by ospf only. If you look at the routing table on router 3 it has no route to get back to router 1. In fact router 3 hasn't learned any remote routes. If you do the mutual redistribution you will not need any default routes.

hjor

all right. Thanks again. And apparently I don't need the 172.16.2.32 network statement on router 2, like you said.

So; I configure like this?;

router 1
ospf 1
network 172.16.2.32 0.0.0.31 area 0
network 172.16.1.0 0.0.0.3 area 0
end

router 2
ospf 1
network 172.16.1.0 0.0.0.3 area 0
end

Right?

But there musn't be redistribution between eigrp and ospf! So, I think I must use ip route from router 2 0.0.0.0 0.0.0.0 10.10.1.2 to router 3
AND use default-information originate on router 2. Just like I did. Maybe this is correct and it should work, do you agree?

And like this?;

router 2

eigrp 100
network 10.10.1.0 0.0.0.3
network 172.30.1.0 0.0.0.255
no auto-summary
end

router 3
eigrp 100
network 10.10.1.0 0.0.0.3
network 172.30.2.0 0.0.0.255
no auto-summary
end

right?

But after all these configurations do I still have that interface fastethernet 0/0 problem on router 3 what Dtlokee said?

networker050184

Are the ethernet interfaces connected to each other?

hjor

yes they are. And if they weren't?

are the configs ok now?

networker050184

If they are connected they need to be on the same subnet like dtlokee stated. The only reason they say up up with out being on the same subnet is the no keepalive that you have configured on them. If they are not connected its good.

With your single default route you will not be able to communicate between router 1 and 3. Try to ping an address on router 3 from router 1. Even though you have a route to the subnets on router 3, router 3 has no route back to router 1. This could be solved by redistibuting ospf into eigrp or adding a default route from router 3 to router 2.
