hi,
i have a question about IS-IS redistribution behavior.
<R3>------ <R1> ------<R2>------<R4>
| --<OSPF>--| -<IS-IS-L2>-|-<EIGRP>-|
R1 --> lo0 1.1.1.1 255.255.255.0
R2 --> lo0 2.2.2.2 255.255.255.0
R3 --> lo0 3.3.3.3 255.255.255.0
R4 --> lo0 4.4.4.4 255.255.255.0
i did reditribute IS-IS into OSPF in R1, and EIGRP into ISIS also in R2
in this case, R3 must see R1-R2 route, R2-R4 route and all loopback int.
but R3 coudln't see R1'loopback and R1-R2 route.
R4's loopback interface and R2-R4 route ware redistributed into OSPF corectly...
R1's routing table(ISIS) and cofigs
-----------------------------------------
R1#sh ip ro is
2.0.0.0/24 is subnetted, 1 subnets
i L2 2.2.2.0 [115/20] via 135.2.21.2, FastEthernet0/0
4.0.0.0/24 is subnetted, 1 subnets
i L2 4.4.4.0 [115/10] via 135.2.21.2, FastEthernet0/0
135.2.0.0/24 is subnetted, 3 subnets
i L2 135.2.42.0 [115/10] via 135.2.21.2, FastEthernet0/0
R1#sh run | b router ospf 1

end
-----------------------------------------
R3's routing table.
ISIS route from R2 is redistribute correctly,
but no R1's ISIS route is redistributed.....
-----------------------------------------
R3#sh ip ro os
2.0.0.0/24 is subnetted, 1 subnets
O E2 2.2.2.0 [110/99] via 135.2.31.1, 00:03:53, FastEthernet0/1
4.0.0.0/24 is subnetted, 1 subnets
O E2 4.4.4.0 [110/99] via 135.2.31.1, 00:03:53, FastEthernet0/1
135.2.0.0/24 is subnetted, 2 subnets
O E2 135.2.42.0 [110/99] via 135.2.31.1, 00:03:53, FastEthernet0/1
-----------------------------------------
my question is whether ISIS redistribute ISIS route that connected in
thmself into
other routing protocol or not.
i read IOS doc, but i coudlnt find about this issue.
please give me your advice.
regards
KF
