MAC ACLs are only valid for non-IP Traffic. See this link:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/1
2.2_25_see/configuration/guide/swacl.html#wp1177176

So to accomplish what you want you have to do it at IP level:

!
ip access-list extended NO-RIP
 deny ip any host 224.0.0.9
 permit ip any any
!
interface GigabitEthernet0/1
 ip access-group NO-RIP in
!

I don't see right now other options.

Subject: filtering multicast frames

Hi

Has anybody got an idea what I'm doing wrong here please?

mac access-list extended rip

 deny any host 0100.5e00.0009

 deny any any

interface FastEthernet0/24

 switchport access vlan 110

 switchport mode access

 mac access-group rip in

Seems a simple task to me but I figure I must be missing something vital.

Thanks in advance

Alex
