By default, the neighbor tracking
function is disabled.
8. Enable dropping hello
messages without the
Generation ID option.
ipv6 pim require-genid
By default, an interface accepts
hello message without the
Generation ID option.
Configuring common IPv6 PIM timers
IPv6 PIM routers periodically send hello messages to discover IPv6 PIM neighbors, and maintain IPv6
PIM neighbor relationship.
After receiving a hello message, an IPv6 PIM router waits for a random time period before sending a
hello message. This random time period is smaller than the maximum delay for sending hello messages,
