This issue was raised here a few years back in the archives, but wasn't
resolved.
R1 redistributes ISIS into OSPF:
router ospf 1
redistribute isis level-1-2 subnets
ISIS is configured on the local router as such:
router isis
net 49.0001.0000.0000.0001.00
passive-interface lo0
int s1/0.1
ip router isis
isis circuit-type level-1-2
ISIS puts these two interfaces into its level-1 database. It also receives a
route from an ISIS neighbor, R2. (I can post up the ISIS database if any wants
to see it).
The only ISIS route that finds its way into OSPF is the route from R2. The
directly connected ISIS routes (the serial subinterface and loopback) do not
make into the OSPF external route table. In the archive, it seems to been have
determined that OSPF would not import routes if those same routes were also
directly connected. However I substitued ISIS with EIGRP and the routes were
successfully introduced into OSPF. RIP worked the same way ( I did not
redistribute connected into OSPF).
I also tried fiddling around with the isis circuit types, making the serial
subinterface a level-2 only circuit, as well as the ISIS routing as level-2
only, with no results.
Am I missing something embarrassingly obvious? Help !
Thanks,
Joe
