35.6.22.7 Configure the Static RP
In a small-scale network, you can use the static RP to use the PIM-SM, which requires that
the static RP configuration of all devices in the PIM-SM domain must be consistent to ensure
the uniqueness of PIM-SM multicast routes.
If a device in the PIM-SM domain runs BSR, search RP accoording to the order:
If override is configured, the static RP is prior to the RP in the RP mapping table distributed
by BSR;
If override is not configured, the RP mapping table distributed by BSR is prior to the static
RP.
Please execute the following commands in the global configuration mode:
Please pay attention to following points when using this command:
If both the BSR and static RP configurations are effective, the dynamic
configuration takes priority.
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 can be configured for several times.
If several addresses can be configured for RP, the high address is
firstly used.
Only the permitted filtered addresses defined in the ACL are invalid
multicast groups. The default filtering 0.0.0.0/0 is to filter all multicast
groups 224/4.
After the configuration, the static RP source address is inserted to the
tree of group-based static RP group. Each static multicast group
maintains the link table structure of a static RP group. The link tables
are ordered decreasingly by the IP addresses. When an RP is selected
in a group, the first element, namely, the RP with the highest IP
address is firstly selected.
To delete a static RP address, the address from all groups is deleted,
and one address is selected from the existing tree structure as the RP
address.
