Guys, Thanks for the tips.
The problem was the destination of r1 tunnel interface was not pingable. It
was not in the routing table. Which leads me to my second question, after
investigating this, This loopback 5.5.5.5 is used as a router id. So r4
should be redistributing ospf routes to r1 via eigrp. Since he has it as a
/32 route he is not redistributing into eigrp for some reason. Does anyone
know why? or how to get this route into eigrp so r1 can see it. When I
changed the tunnel everything kicked in. also there was an error in the
mask on the tunnels as someone said. If anybody knows why this /32 won't
get redistributed I would like to know.
Once again thanks. Now I am going to try to encrypt the traffic!!!

Subject: Tunneling ISIS
Hi,
I am trying to tunnel ISIS through and ospf environment. This is what I have
done. The layout is r1 -- r4 -- r5. r1 -- r4 is EIGRP; r4 -- r5 is OSPF
via frame link. I am doing mutual redistribution, and all routes are seen.
Now I have created a loopback on r1 and a loopback on r5 which are not in
any routing process. I want to create a tunnel between r1 -- r5 and be able
to ping these loopbacks via ISIS.
What I have done
R1
clns routing
router isis
net 49.0001.1111.1111.1111.00
interface Loopback4
ip address 1.1.1.1 255.255.255.0
int lo5
ip addr 10.2.2.2 255.255.255.0
interface Tunnel1
ip address 10.0.0.2 255.255.255.0
ip router isis
tunnel source 1.1.1.1
tunnel destination 5.5.5.5
R5
clns routing
router isis
interface Loopback0
ip address 5.5.5.5 255.255.255.0
interface Loopback1
ip address 10.1.1.1 255.255.255.0
ip router isis
interface Tunnel3
ip address 10.0.0.1 255.255.255.252
ip router isis
tunnel source 5.5.5.5
tunnel destination 1.1.1.1
Keep in mind other stuff is in the config, I pulled out the appropriate
info. I expected to see a ISIS route on these routers with the loopback
there. Once I got this working, I was going to try to encrypt the traffic.
Can someone explain the problem, am I missing something.
