Example of PIM-DM status refresh configuration
Refer to configure status refresh.
Example of administrative boundary configuration
The following example demonstrate how to configure administrative boundary of a port:
interface ethernet 0/0
ip multicast boundary acl
ip access-list standard acl
permit 192.168.20.97 255.255.255.0
2. Example of multicast Helper configuration
The following example demonstrates how to configure multicast helper.
Configuration on the router is as below: Configure ip directed-broadcast on port e0 of the first hop
router to allow direct broadcast message processing. Configure ip multicast helper-map broadcast
230.0.0.1 testacl1 to allow translating udp broadcast messages whose port number is 4000 and sent
by source address 192.168.20.97/24 into multicast messages whose destination address is 230.0.0.1
for transmitting.
Configure ip directed-broadcast on port e1 of the last hop router to allow direct broadcast message
processing. Configure ip multicast helper-map 230.0.0.1 172.10.255.255 testacl2 to allow translating
udp multicast messages whose port number is 4000, destination is 230.0.0.1 and sent by source
address 192.168.20.97/24 into broadcast messages whose destination address is 172.10.255.255 for
transmitting.
On the first hop router connected with source broadcast network:
interface ethernet 0
ip directed-broadcast
ip multicast helper-map broadcast 230.0.0.1 testacl
ip pim-dm
!
ip access-list extended testacl permit udp 192.168.20.97 255.255.255.0 any
ip forward-protocol udp 4000
On the last hop router connected with destination broadcast network:
interface ethernet 1
ip directed-broadcast
ip multicast helper-map 230.0.0.1 172.10.255.255 testacl2
ip pim-dm
