LAB 9 2.7.....OSPF to ISIS redistribution

Hi,

 

I am facing problem with redistribution from OSPF to ISIS.

I have redistributed the route on R1 from OSPF to ISIS as per solution provided.But i am not able to see the route of  router R4 Loopback on R3.

Can any one please provide is there anything extra need to do while redistributing route from OSPF to ISIS ?

    Always remember ISIS has L1 & L2 database and they do not mix. So redistribution must be done to both L1 & L2. Also from ISIS it does not redistribute it’s interfaces so need to be redistributed as connected into the protocol you are redistributing too



    Thanks

  • Hi Ciscokid, I tried to perform "redistribute connected level-2" on R1 under the ISIS process, but R4 is still unable to see the 150.1.101.0/24 and 172.16.0.0/31 routes. And when I perform "show isis database detail" on R1, it seems that only interfaces which do not have the "ip router isis" command will be redistributed as connected.

    Any idea where went wrong?

    Thanks.

  • Hi Zey,

    Try including the ATM3/0.1 and Serial2/1 interfaces in your OSPF redistribution route-map on R1.  It should look something like this:

    !
    route-map REDIST_OSPF_CONN permit 10
     match interface Loopback0 ATM3/0.1 Serial2/1

    After adding these interfaces, I was then able to see the 150.1.101.0/24 and 172.16.0.0/31 networks on R4.
