This dosn't resolve the problem I've already tried it:
R7:
router isis
redistribute ospf 1 match internal external 1 external 2
net 00.0000.0000.0000.00
is-type level-2-only
!
R8:
R8#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter
area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
200.0.0.0/32 is subnetted, 2 subnets
C 200.0.0.8 is directly connected, Loopback0
i L2 200.0.0.7 [115/10] via 150.50.5.68, Serial0/0
150.50.0.0/16 is variably subnetted, 3 subnets, 3 masks
C 150.50.4.0/24 is directly connected, FastEthernet0/0
i L2 150.50.7.0/25 [115/10] via 150.50.5.68, Serial0/0
C 150.50.5.64/27 is directly connected, Serial0/0

Objet : Re: Mutual Redistribution
After you type in "redistribute ospf 1" do a question mark.
There is options about which types ospf routes to redistribute, ie,.
which lsa's.
If you want to shove them all in, try " redist ospf 1 int ex1 ex 2"
