3Com Switch 8800 Configuration Guide Chapter 29 PIM-SM Configuration
29-6
Operation Command
Remove the
candidate-RP configured undo c-rp { interface-type interface-number | all }
When configuring RP, if the range of the served multicast group is not specified, the RP
will serve all multicast groups. Otherwise, the range of the served multicast group is the
multicast group in the specified range. It is suggested to configure Candidate RP on the
backbone router.
29.2.7 Configuring Static RP Static RP serves as the backup of dynamic RP, so as to improve network robusticity.
Perform the following configuration in PIM view.
Table 29-4 Configuring static RP
Operation Command
Configure static RP static-rp rp-address [ acl-number ]
Remove the configured static RP undo static-rp
Basic ACL can control the range of multicast group served by static RP.
If static RP is in use, all routers in the PIM domain must adopt the same configuration. If
the configured static RP address is the interface address of the local router whose state
is UP, the router will function as the static RP. It is unnecessary to enable PIM on the
interface that functions as static RP.
When the RP elected from BSR mechanism is valid, static RP does not work.
29.2.8 Configuring the PIM-SM Domain Border After the PIM-SM domain border is configured, bootstrap messages can not cross the
border in any direction. In this way, the PIM-SM domain can be split.
Perform the following configuration in VLAN interface view.
Table 29-5 Configuring the PIM-SM domain border
Operation Command
Set the PIM-SM domain border pim bsr-boundary
Remove the PIM-SM domain border configured undo pim bsr-boundary
