DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-6
established adjacency relationship with that neighbor.
To configure the PIM-SM neighbor filtering function, run the following command in
the interface mode:
Command Function
DES-7200(config-if)# ip pim neighbor-filter
access-list
Enable the PIM neighbor filtering
function on the interface.
DES-7200(config-if)# no ip pim
neighbor-filter access-list
Disable the PIM neighbor filtering
function on the interface.
The PIM-SM neighbor filtering function is disabled by default on an interface.
Note
A device can become the PIM-SM neighbor of the interface only when its IP
address matches the associated ACL whose rule is permit.
6.3.9 Configuring the Priority of DR
This command is used to configure the priority of the designated router (DR),
higher weight means higher priority.
To configure the priority of DR, run the following commands in the interface mode:
Command Function
DES-7200(config-if)# ip pim dr-priority
priority-value
Configure the priority in the range of 0 to
4294967294.
DES-7200(config-if)# no ip pim dr-priority
priority
Restore the DR priority to the default
value, namely 1.
6.3.10 Configuring Static RP
In a small network, you can configure static RP to use PIM-SM. This requires all
the devices in the PIM-SM domain have the same static RP configuration and
ensure no ambiguity of the PIM-SM multicast routes.
To configure static RP, execute the following commands in the global
configuration mode:
Command Function
DES-7200(config)# ip pim rp-address
rp-address [access-list]
Configure static RP on the local device.
DES-7200(config)# no ip pim rp-address
rp-address [access-list]
Remove the static RP configuration.
Caution
Attention should be attained to following points when using this command:
If both the BSR and static RP configurations take effect simultaneously, the
static RP takes precedence.
The static RP address can be configured for multiple multicast groups (by ACL)
or all multicast groups (not by ACL). However, a static RP address cannot be
configured for several times.
If more than one static RP are configured for a multicast group, the one with the
highest IP address takes effect.
Only the permitted addresses defined in the ACL are invalid multicast groups.
By default, 0.0.0.0/0 refers to filter all multicast groups (224/4).
After configuration, the static RP source address is inserted into the tree of
