Only the last hop DP and the RP can actively switch over to
the source shortest path tree. By default, when the RP
receives the first registration information, it will start the
switchover. For the last hop DR, configure the switchover
threshold strategy of the source shortest path tree, with the
unicast group as control granularity. If the switchover
threshold is set to infinity, switchover does not occur. By
default, switchover must take place if traffic exists.
2. To set the DR priority, use ip pim dr-priority <priority>
command in interface configuration mode as shown in
Table
392.

ip pim dr-

This sets the DR priority
Result: This sets the DR priority.
A DR must be selected in a shared (or Multi-Access) network
segment. The router with the highest priority will win the
selection. If the priorities are identical, the router with the
greatest IP address will be selected.
In the shared network segment connected with the multicast
data source, only the DR can send the registration information to
the RP. In the shared network segment connected with the
receiver, only the DR can respond to IGMP joining/leaving
messages, and send PIM joining/pruning messages to upstream.
The priority of a router is contained in the Hello message
exchanged with neighbors. The default value is 0.
3. To configure an interface to be the PIM domain border, use
ip pim bsr-border command in interface configuration
mode as shown in
