Here is the solution I came up with.
R4 is my distribution between OSPF and IS-IS. L0, S0 and S1 are all
configured for IS-IS and To0 is in OSPF Area 1.
R4
hostname R4
!
!
!
!
!
!
ip subnet-zero
no ip domain-lookup
!
!
!
!
!
!
interface Loopback0
ip address 200.10.10.4 255.255.255.255
ip router isis
!
interface Serial0
no ip address
encapsulation frame-relay
frame-relay lmi-type cisco
!
interface Serial0.1 point-to-point
bandwidth 64
ip address 172.100.10.6 255.255.255.252
ip router isis
frame-relay interface-dlci 107
isis password cisco level-1
!
interface Serial1
bandwidth 64
ip address 172.100.10.24 255.255.255.240
ip router isis
clockrate 64000
isis password cisco level-1
isis priority 127
!
interface TokenRing0
ip address 10.10.10.4 255.255.255.0
ring-speed 16
!
router ospf 100
log-adjacency-changes
redistribute connected subnets route-map ospf-connected
redistribute isis level-1 subnets
passive-interface Serial0
passive-interface Serial1
network 10.10.10.0 0.0.0.255 area 1
!
router isis
redistribute ospf 100 metric-type external
net 50.0000.0000.0000.0002.00
!
ip classless
ip http server
!
access-list 10 deny 10.10.10.0 0.0.0.255
access-list 10 permit any
route-map ospf-connected permit 10
match ip address 10
When I double checked the routes in OSPF I was seeing all of the routes in
IS-IS except the networks that were directly connected in R4. I created a
route-map to redistribute the connected networks on R4 except for the Token
Ring interface since it is already in OSPF.
That did the trick as far as pinging across domains is concerned.
Was this the right way to do it or can anyone else think of another way?
