Configuration Examples; Changing An Rpf Route - HP 6125XLG Configuration Manual

Task
Display multicast
forwarding table
information.
Display information about
the multicast routing table.
Display information about
the static multicast routing
table.
Display RPF route
information about the
multicast source.
Clear forwarding entries
from the multicast
forwarding table.
Clear routing entries from
the multicast routing table.
NOTE:
When a forwarding entry is removed, the associated routing entry is also removed. When a routing entry
is removed, the associated forwarding entry is also removed.

Configuration examples

Changing an RPF route

Network requirements
As shown in
A, Switch B, and Switch C run OSPF. Typically, the receiver host can receive the multicast data from the
source through the path: Switch A to Switch B, which is the same as the unicast route.
Perform the configuration so that the receiver host receives the multicast data from the source through the
path: Switch A to Switch C to Switch B, which is different from the unicast route.
Command
display multicast forwarding-table [ source-address [ mask { mask-length |
mask } ] | group-address [ mask { mask-length | mask } ] | incoming-interface
interface-type interface-number | outgoing-interface { exclude | include |
match } interface-type interface-number | slot slot-number | statistics ] *
display multicast routing-table [ source-address [ mask { mask-length | mask } ]
| group-address [ mask { mask-length | mask } ] | incoming-interface
interface-type interface-number | outgoing-interface { exclude | include |
match } interface-type interface-number ] *
display multicast routing-table static [ source-address { mask-length | mask } ]
display multicast rpf-info source-address [ group-address ]
reset multicast forwarding-table { { source-address [ mask { mask-length |
mask } ] | group-address [ mask { mask-length | mask } ] | incoming-interface
{ interface-type interface-number } } * | all }
reset multicast routing-table { { source-address [ mask { mask-length | mask } ] |
group-address [ mask { mask-length | mask } ] | incoming-interface
interface-type interface-number } * | all }
Figure 18, PIM-DM runs in the network. All switches in the network support multicast. Switch
