ANCP IGMP Configuration Example

In the following example (Figure 18), two subscribers access individual multicast channels through cross connections (branches) that occur on the access node.

Figure 18: Using ANCP with an Access Node

To configure the example, use the following general procedures:

Note: This example provides general information for configuring ANCP mapping. For detailed information about creating OIF maps, see Configuring Transactional Multicast for IGMP.

1. Configure an OIF map for the access node that maps each multicast group to an outgoing interface.
2. Define ANCP parameters.
3. Enable ANCP to listen to OIF mapping events from IGMP in this virtual router.
4. Create a listening TCP socket in the virtual router (TCP port 6068).
5. Define ANCP neighbor parameters.

   Note: The ID is a 48 bit quantity that identifies the ANCP neighbor.

6. Configure the ANCP multicast labels (input labels) on the corresponding outgoing interfaces.
7. Configure the ANCP output labels, the neighbor information on the subscriber interfaces, and apply the OIF map.

   When Subscriber A requests to join 232.1.1.1, ANCP transmits an add branch message with the corresponding input and output labels that cross-connect
   port 3 and port 6 on Access Node 1.
