The set protocols pimsm4 bootstrap cand-rp group-prefix rp-holdtime command configures the holdtime for a received Advertisement message on a BSR.
set protocols pimsm4 bootstrap cand-rp group-prefix <IPv4Net> rp-holdtime <interval>
Specifies the range of multicast group that can serve on a C-RP. The value is an IPv4 multicast subnet address in the address/prefix-length format, e.g., 126.96.36.199/8.
Specifies the timeout time during which C-BSR waits for the Bootstrap message to be sent by BSR. The value is an integer that ranges from 0 to 65535, in seconds. The default value is 150s.
The RP holdtime configuration should be greater than 60s, considering that the C-RP sends the Advertisement message to the BSR with an interval of 60s.
When interval is set on a C-RP, the C-RP encapsulates interval in an Advertisement message and sends it to the BSR. The BSR obtains this 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 and will remove it from the set of possible RPs.
