Configuration Examples; Changing An Rpf Route - HP A6600 Configuration Manual

To do...
Display RPF route information of
the specified multicast source.
Display minimum TTL required
for a multicast packet to be
forwarded.
Display static multicast MAC
address entries.
Clear forwarding entries from
the multicast forwarding table.
Clear routing entries from the
multicast routing table.
The reset command clears the information in the multicast routing table or the multicast forwarding table,
and thus might cause failure of multicast transmission.
When a routing entry is deleted from the multicast routing table, the corresponding forwarding entry will
also be deleted from the multicast forwarding table.
When a forwarding entry is deleted from the multicast forwarding table, the corresponding routing entry
will also be deleted from the multicast routing table.

Changing an RPF route

Network requirements
PIM-DM runs in the network. All routers in the network support multicast.
•
Router A, Router B and Router C run OSPF.
•
Typically, Receiver can receive the multicast data from Source through the path Router A – Router B,
•
which is the same as the unicast route.
Perform the following configuration so that Receiver can receive the multicast data from Source
•
through the path Router A – Router C – Router B, which is different from the unicast route.
Use the command...
display multicast [ all-instance | vpn-instance
vpn-instance-name ] rpf-info source-address
[ group-address ] [ | { begin | exclude | include }
regular-expression ]
display multicast [ all-instance | vpn-instance
vpn-instance-name ] minimum-ttl [ interface-type
interface-number ] [ | { begin | exclude | include }
regular-expression ]
display mac-address [ mac-address [ vlan vlan-id ] |
[ multicast ] [ vlan vlan-id ] [ count ] ] [ | { begin | exclude
| include } regular-expression ]
reset multicast [ all-instance | vpn-instance
vpn-instance-name ] forwarding-table { { source-address
[ mask { mask | mask-length } ] | group-address [ mask
{ mask | mask-length } ] | incoming-interface
{ interface-type interface-number | register } } * | all }
reset multicast [ all-instance | vpn-instance
vpn-instance-name ] routing-table { { source-address
[ mask { mask | mask-length } ] | group-address [ mask
{ mask | mask-length } ] | incoming-interface
{ interface-type interface-number | register } } * | all }
