ALU - Proxy IGMP

Foreward: An ALU is an Autonomous Learning Unit, you can read this post to learn more about them.

Proxy IGMP:

You have two routers connected back to back via a PPP serial connection.  A multicast server in the 1.1.2.0 subnet will be streaming a video broadcast soon.  Users in subnet 1.1.3.0 will need to see that broadcast.  The administrator of R3 will not allow PIM to be ran on his router.  Allow users on the 1.1.3.0 subnet to view the multicast video session.












Highlight the section below for the answer:


Solution:

R3:

interface FastEthenet0/0

  ip igmp helper-address 1.1.23.2

 

R2:

ip multicast-routing

access-list 1 deny 1.1.23.3

interface Serial0/1

  ip pim sparse-dense-mode

  ip pim neighbor-filter 1

interface FastEthernet0/0

  ip pim sparse-dense-mode
