R3303-HP HSR6800 Routers IP Multicast Command Reference

117
Default command level
2: System level
Parameters
interval: Specifies a C-RP timeout timer in seconds, in the range of 1 to 65535.
Usage guidelines
Because a non-BSR router refreshes its C-RP timeout timer through BSR bootstrap messages, to prevent
loss of C-RP information in BSR bootstrap messages, make sure the C-RP timeout timer is not smaller than
the interval at which the BSR sends bootstrap messages. The recommended C-RP timeout setting is 2.5
times the BS period or longer.
Examples
# Set the global C-RP timeout timer to 200 seconds on the public network.
<Sysname> system-view
[Sysname] pim
[Sysname-pim] c-rp holdtime 200
# Set the global C-RP timeout timer to 200 seconds in VPN instance mvpn.
<Sysname> system-view
[Sysname] pim vpn-instance mvpn
[Sysname-pim-mvpn] c-rp holdtime 200

groups.
