R6 run ospf/igrp, R6/R3 run igrp, right ?
I think you can do the following:-
Ie turn off sp
- Turn off R6/R3 link sp at R6.
- At R6, sse filter to replace the function of SP.
- At R6, create secondary ip address with /24 at R6/R3 link
Now you will see that the /24 from ospf advertise to R3, but it become /28 rout
e in R3, ie with some missing subnets. This is not a very good solution.
If you want to see the /24 in R3, then do the same steps for R3 and now we shou
ld see the /24 route in R3.

Subject: secondary address no longer works?
Am I the only person have troubles with the secondary address? I have
the following (everything is in 172.16.x.x/16):
24.1/24----\
R2--2.2/24-ospf-2.1/24--R6--1.1/28-igrp-1.2/28--R3--3.1/28
28.1/28----/
When I add the 2nd address 36.1/24 and 36.2/24 on r6 and r3, 24.1/24 is
not seen in 'debug ip igrp trans'. When I switched the primary with
the secondary addresses, i.e. /28 is secondary address and /24
is primary address, only /24 routes can be seen in the debug. It looks
like routes can only be distributed via primary interface.
The problem was fixed by using the tunnel interface. But I'm wondering
if you have seen this problems. I've checked the archives and someone
said the secondary addresses would stop working if you reboot the
router. I've used it in the past without any problems, but wondering
if this is a bad choice.
Thanks,
Chang
