DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-8
6.3.14 Configuring Candidate RP
Candidate RP advertisement is sent to the BSR at intervals and then propagated
to all the PIM-SM devices in the domain, and thus ensuring the uniqueness of RP
mapping.
To configure the candidate RP, execute the following commands in the global
configuration mode:
Command Function
DES-7200(config)# ip pim rp-candidate
interface-type interface-number [priority
priority-value] [interval interval-seconds]
[group-list access-list]
Configure the device as the candidate
RP.
priority-value: in the range of 0 to 255,
192 by default
interval-seconds: in the range 1 to 16383,
60s by default
access-list: All multicast groups are
permitted, that is 224/4
DES-7200(config)# no ip pim
rp-candidate interface-type
interface-number
Remove the candidate RP configuration.
Note
You can use the ACL to specify a port as the candidate RP of a particular
group. It should be noted that the group calculation is based on the permit ACE
only, not the deny ACE.
Caution
The source IP address of ACE is used as the specific group range for matching.
6.3.15 Checking the Reachability for RPs
This command detects whether the RPs sent from DR can reach the destination
device.
To check the reachability of RPs, execute the following commands in the global
configuration mode:
Command Function
DES-7200(config)# ip pim
register-rp-reachability
Check the reachability of RPs.
DES-7200(config)# no ip pim
register-rp-reachability
Disable this function.
6.3.16 Filtering the Addresses of Register Packets
Execute the ip pim accept-register list access list command to filter the pair of
source IP address and multicast group IP address of reached register packets.
Otherwise, every reached register packet is permitted.
To filter the addresses of register packets, execute the following commands in the
global configuration mode:
Command Function
