PIM DR Election
On advertisement interfaces, the PIM appointed router (DR) is amenable for sending PIM Register,
Join, and Prune letters against the RP. In IPv6 PIM, DR acclamation works absolutely as in IPv4. That
is, by default, the PIM router with the accomplished unicast IPv6 abode becomes the DR. You can also
statically configure the PIM DR by allotment antecedence values. (The accomplished antecedence wins the
election.) If the DR fails, the PIM router with the accomplished actual antecedence becomes the DR. The
IPv6 abode is afresh the tie-breaker.
