crp-policy (PIM view)
Use crp-policy to configure a legal C-RP address range and the range of served multicast groups, in
order to guard against C-RP spoofing.
Use undo crp-policy to remove the restrictions in C-RP address ranges and the ranges of served multicast
groups.
Syntax
crp-policy acl-number
undo crp-policy
Default
No restrictions are defined for C-RP address ranges and the address ranges of served groups. Namely,
all received C-RP messages are accepted.
Views
Public network PIM view
Default command level
2: System level
Parameters
acl-number: Specifies an advanced ACL, 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.
Usage guidelines
The crp-policy command filters the multicast group ranges advertised by C-RPs based on the group
prefixes. For example, if the multicast group range that a C-RP advertises is 224.1.0.0/16 and the legal
group range that the crp-policy command defines is 224.1.0.0/30, the multicast groups in the range of
224.1.0.0/16 can pass.
Examples
# On the public network, configure a C-RP policy so that only devices in the address range of 1.1.1.1/24
can be C-RPs that serve multicast groups in the address range of 225.1.1.0/24.
