Another option is for both routers to redistribute connected. Split horizon
will prevent them from advertising to each other but they will then
advertise to other neighbors.

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
