Configuring A Multicast Routing Policy; Configuring A Multicast Forwarding Range - HP 4800G Series Configuration Manual

Configuring a Multicast Routing Policy

You can configure the router to determine the RPF route based on the longest match principle. For
details about RPF route selection, refer to
By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery
when multiple data flows are handled.
Configuring a multicast routing policy
Follow these steps to configure a multicast routing policy:
To do...
Enter system view
Configure the device to select
the RPF route based on the
longest match
Configure multicast load
splitting

Configuring a Multicast Forwarding Range

Multicast packets do not travel without a boundary in a network. The multicast data corresponding to
each multicast group must be transmitted within a definite scope. Presently, you can define a multicast
forwarding range by:
Specifying boundary interfaces, which form a closed multicast forwarding area, or
Setting the minimum time to live (TTL) value required for a multicast packet to be forwarded.
Setting the minimum TTL is not supported on 3Com Switch 4800G.
You can configure a forwarding boundary specific to a particular multicast group on all interfaces that
support multicast forwarding. A multicast forwarding boundary sets the boundary condition for the
multicast groups in the specified range. If the destination address of a multicast packet matches the set
boundary condition, the packet will not be forwarded. Once a multicast boundary is configured on an
interface, this interface can no longer forward multicast packets (including packets sent from the local
device) or receive multicast packets.
Follow these steps to configure a multicast forwarding range:
To do...
Enter system view
Enter interface view
RPF check process.
Use the command...
system-view
multicast longest-match
multicast load-splitting
{ source | source-group }
Use the command...

1-8
