Hi Bruce -
Can you tell me where you saw this? I have not seen the "ip multicast
boundary" with an <in/out option> in any release, so I am confused.
R1(config-if)#ip multi b test ?
filter-autorp Filter AutoRP packet contents
<cr>
R1(config-if)#ip multi b test
The ACL sort of makes sense, but not all of it - 232/8 is the default
SSM group range, so this ACL does permit the two SGs. I don't
understand the first line "host 0.0.0.0" or there should be a UDP
related ACL just for one SG.
HTH

Hi Group,
Please help me, I can't understand this example at all:
The following example permits outgoing traffic for (181.1.2.201,
232.1.1.1) and
(181.1.2.202, 232.1.1.1) and denies all other (S,G)s.
ip access-list extended acc_grp1
permit ip host 0.0.0.0 232.1.1.1 0.0.0.255
permit ip host 181.1.2.201 host 232.1.1.1
permit udp host 181.1.2.202 host 232.1.1.1
permit ip host 181.1.2.202 host 232.1.1.1
deny igmp host 181.2.3.303 host 232.1.1.1
interface ethernet 2/3
ip multicast boundary acc_grp1 out
Thanks.
