Figure 12-8. Sample Multicast Configuration
1. Enable multicast routing:
ProCurve(config)# ip multicast-routing
2. Set the helper address, which is the address of the multicast router. (See
Figure 12-8.)
Syntax: ip mcast-stub helper-address <A.B.C.D>
For example:
ProCurve(config)# ip mcast-stub helper-address 10.1.1.2
The local router must, of course, know a route to this address.
3. Move to the configuration mode context of the downstream interface.
(See Figure 12-8.)
Syntax: interface <interface ID>
4. Enable IGMP and multicast forwarding.
ProCurve(config-eth 0/1)# ip mcast-stub downstream
5. Enable IGMP proxy to the helper address.
ProCurve(config-eth 0/1)# ip mcast-stub helper-enable
6. If so desired, configure another downstream interface. Repeat steps 3
through 5.
