c-rp holdtime (PIM view)
Syntax c-rp holdtime interval
undo c-rp holdtime
View Public instance PIM view, VPN instance PIM view
Parameter interval: C-RP timeout in seconds, with an effective range of 1 to 65,535.
Description Use the
c-rp holdtime command to configure the global C-RP timeout time,
namely the length of time the BSR waits before it must receive a C-RP-Adv
message.
Use the
undo c-rp holdtime command to restore the default setting.
By default, the C-RP timeout time is 150 seconds.
Because a non-BSR router refreshes its C-RP timeout time through BSR bootstrap
messages, to prevent loss of BSR bootstrap messages, make sure that the C-RP
timeout time is not smaller than the interval at which the BSR sends bootstrap
messages. The recommended C-RP timeout setting is 2.5 times the bootstrap
interval or longer.
Related command: c-rp (PIM view) and c-bsr interval (PIM view).
Example # Set the global C-RP timeout time to 200 seconds in the public instance.

crp-policy (PIM view)
Syntax crp-policy acl-number
undo crp-policy
View Public instance PIM view, VPN instance PIM view
Parameter acl-number: Advanced ACL number, in the range of 3000 to 3999. When the ACL
is defined, the source keyword in the rule command specifies the address of a
C-RP and the destination keyword specifies the address range of the multicast
groups that the C-RP will serve.
Description Use the
crp-policy command to configure a legal C-RP address range and the
range of served multicast groups, so as to guard against C-RP spoofing.
