In an ACL, the source field specifies the multicast group range to which the static RP is designated. If you specify a VPN instance in the ACL, the ACL does not take effect. The other optional parameters except the fragment keyword and the time-range keyword are ignored. When the ACL rules referenced by a static RP change, new RPs must be elected for all multicast groups. You can configure multiple static RPs by using this command multiple times. However, if you specify the same static RP address or reference the same ACL in the command, the most recent configuration takes effect. If you configure multiple static RPs for the same multicast group, the static RP with the highest IP address is used.

The configurations made in PIM view are effective on all interfaces, and the configurations made in interface view are effective on only the current interface. If you set the interval in both PIM view and interface view, the configuration in interface view always takes precedence. 93

In an ACL, the source field specifies the multicast group range to which the static RP is designated. If you
specify a VPN instance in the ACL, the ACL does not take effect. The other optional parameters except
the
fragment
keyword and the
time-range
keyword are ignored.
When the ACL rules referenced by a static RP change, new RPs must be elected for all multicast groups.
You can configure multiple static RPs by using this command multiple times. However, if you specify the
same static RP address or reference the same ACL in the command, the most recent configuration takes
effect. If you configure multiple static RPs for the same multicast group, the static RP with the highest IP
address is used.
Examples
# Configure the interface with the IP address of 11.110.0.6 as a static RP for the multicast groups
225.1.1.0/24, and give priority to this static RP when conflicts exist between static and dynamic RPs.

Parameters
interval
: Sets the interval (in seconds) for sending hello messages, in the range of 0 to 18000. A value
of 0 means that no hello messages are sent.
Usage guidelines
You can set the interval for sending hello messages in PIM view or interface view. The configurations
made in PIM view are effective on all interfaces, and the configurations made in interface view are
effective on only the current interface. If you set the interval in both PIM view and interface view, the
configuration in interface view always takes precedence.
