Sending Multicasts Over The Tunnel - HP 7102dl - ProCurve Secure Router Configuration Manual

4. Enable OSPF on the local networks, including the tunnel's network:
ProCurve(config)# router ospf
ProCurve(config-ospf)# network 192.168.1.0 0.0.0.255 area 0
ProCurve(config-ospf)# network 192.168.10.0 0.0.0.3 area 0

Sending Multicasts over the Tunnel

You can configure Protocol Independent Multicast-Sparse Mode (PIM-SM) on
the tunnel interface to tunnel multicasts through the Internet. Move to the
tunnel interface configuration mode context and enter this command:
ProCurve(config-tunnel 1)# ip pim sparse-mode
You should also configure the RP set, which must match the set configured
on every other in the PIM domain. See Chapter 13: Configuring Multicast
Support with PIM-SM for more information on configuring PIM-SM.
You can also configure the tunnel interface as an upstream Internet Group
Management Protocol (IGMP) interface:
ProCurve(config-tunnel 1)# ip mcast-stub upstream
The tunnel interface will then join multicast host groups on behalf of con-
nected clients and receive multicasts for these clients from the remote end of
the tunnel. (Enabling PIM-SM on the interface automatically enables the
interface to fulfill all functions that an IGMP upstream interface would fulfill.)
You should also enable multicast routing on the router. For example:
ProCurve(config)# ip multicast
If you are using IGMP proxy on the tunnel interface, you should configure
downstream interfaces that connect to the clients and specify the remote
endpoint of the tunnel as the helper address.
ProCurve(config)# ip mcast-stub helper-address 192.168.10.2
ProCurve(config-eth 0/1)# ip mcast-stub downstream
ProCurve(config-eth 0/1) ip mcast-stub helper-enable
See Chapter 12: Configuring Multicast Support for a Stub Network for more
information on configuring multicasting.
