Oh.. I forget to mention something. On R2's e2 interface, I run
secondary IP address and it will handle both 192.168.2.0/24 and
178.21.34.0/24
Is there any extra step to handle multicast-helper with 2 subnet?
I just use multicast generator to test the scenario. Want to know is
it necessary to use another router to do "rtr test" ? I tried to paste
the configuration on R1 and I can't see any hit on the ACL.
Do anyone can provide sample configration on both ethernet side ? I'm
weak in the knowledge on "ip directed-broadcast"
Thanks a lot!
Ryan
