Hi,
Have a look in the routing table on R7.
Is this route a connected route or an OSPF route.
It will be a connected route.
When you redistribute ospf into ISIS the router looks at the routing table
and gets all the ospf routes and redistributes into ISIS. As this is a
connected route, it will not be in there. You can redistribute connected in
ISIS and that will work.
HTH

Hi,
I can't see your routi-map you are using, have you matched it correctly?
Regards
Lee.

This seem to be the one of my problems with mutual redistribution, this is
related to ospf and other protocols:
this is the senario: configuration of routers, some captures and questions.

Objet : Mutual Redistribution
I am testing out mutual redistribution on the same router other than ISIS
protocol. I realise that directly connected network particpating
in some routing protocol for eg RIP is not being redistributed to OSPF.
And sometimes this is vice versa. I use the same IOS on all routers. I
notices in some CCIE workbook they actually redistribute connected
networks as the model answer when doing mutual redistribution. We all
know the "problem" of ISIS in this scenario but this is happening to
other protocols as well. Have you guys encountered these?
