Usage Guidelines

Usage Scenario

When hold-interval is set on a C-RP, the C-RP encapsulates hold-interval in an Advertisement message and sends it to the BSR. The BSR obtains this hold-interval from the message and starts the timer. If the BSR receives no Advertisement message from the C-RP within the timeout period, the BSR regards the C-RP invalid or unreachable.

Prerequisites

IPv6 multicast routing has been enabled using the multicast ipv6 routing-enable command in the system view.

Precautions

You can also run the c-rp ipv6-address holdtime hold-interval command in the PIM-IPv6 view to configure the advertisement message holdtime while configuring a C-RP. The c-rp holdtime hold-interval configures the global holdtime for Advertisement messages. If both the two commands are configured, the holdtime configured by the c-rp ipv6-address holdtime hold-interval command takes effect.

Example

# In the PIM-IPv6 view, set the holdtime for a received Advertisement message to 100s.
