Broadcast to Multicast - Works for 1 port but not another?

dtcobra22 · ‎11-29-2017

Hi all,

I've pretty much sorted all of my main issues configuring Multicast Helper-Maps but there is one thing I'm having issues with.

I'm using the following config:

ACL:

ip access-list extended CISCO3000

permit udp any host 10.1.1.255 eq 3000

ip access-list extended CISCO4000

permit udp any host 10.1.1.255 eq 4000

ip access-list extended CISCO5000

permit udp any host 10.1.1.255 eq 5000

Interface Gi0/1
ip multicast helper-map broadcast 239.3.3.3 CISCO3000

ip multicast helper-map broadcast 239.4.4.4 CISCO4000

ip multicast helper-map broadcast 239.5.5.5 CISCO5000

I'm using Ostinato packet generator, sending broadcast packets to 10.1.1.255:3000 and I can see the ACL match increment against CISCO3000 which is great. But when I send packets to that broadcast address via port 4000 and 5000 I'm getting no matches against the ACLs CISCO4000 & CISCO5000.

Ideas?

Hello

Have you specified the specific UDP and port to be forwarded?

What igp are you using?
Can you post the config of you first/last hop rtr?
