c-rp holdtime (IPv6 PIM view)
Use c-rp holdtime to configure the global C-RP timeout timer, namely, the time that the BSR waits for a
C-RP-Adv message from C-RPs.
Use undo c-rp holdtime to restore the default.
Syntax
c-rp holdtime interval
undo c-rp holdtime
Default
The C-RP timeout timer is 150 seconds.
Views
IPv6 PIM view
Default command level
2: System level
Parameters
interval: Specifies a C-RP timeout timer in seconds. The value ranges from 1 to 65535.
Usage guidelines
Because a non-BSR router refreshes its C-RP timeout timer through bootstrap messages, to prevent loss of
C-RP information in 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.
<Sysname> system-view
[Sysname] pim ipv6

multicast groups.
