Concept Guide

router with the greatest priority value is the DR. If the priority value is the same for two routers, then the router with the greatest IPv4 or
IPv6 address is the DR. By default, the DR priority value is 192, so the IP address determines the DR.
• Assign a DR priority value.
INTERFACE mode
{ip | ipv6} pim dr-priority priority-value
• Change the interval at which a router sends hello messages.
INTERFACE mode
{ip | ipv6} pim query-interval seconds
• Display the current value of these parameter.
EXEC Privilege mode
show {ip | ipv6} pim interface
