DES-7200 Configuration Guide Chapter 6 PIM-SM
Configuration
6-9
Command Function
DES-7200(config)# ip pim
accept-register list access-list
Filter the pair of source IP address and
multicast group IP address of register
packets.
DES-7200(config)# no pim
accept-register
Remove the configuration.
6.3.17 Configuring the Speed Limit on Sending RPs
This command configures the speed at which the DR sends registration packets
in (S, G). No speed limit is configured by default.
To configure the speed limit on sending RPs, execute the following commands in
the global configuration mode:
Command Function
DES-7200(config)# ip pim
register-rate-limit <1-65535>
Set the maximum number of RP packets
sent per second in the range of 1-65535.
DES-7200(config)# no ip pim
rp-candidate
Remove the configuration.
6.3.18 Calculating the Checksum of Register Packets in Cisco ‘s Way
Execute the ip pim cisco-register-checksum command to calculate the
checksum of register packets in Cisco’s way. Otherwise, the checksum of register
packets is calculated in default way specified by the protocol.
To calculate the checksum of register packets in Cisco’s way, execute the
following command in the global configuration mode.
Command Function
DES-7200(config)# ip pim
cisco-register-checksum [group-list
access-list]
Calculate the checksum of register
packets in Cisco’s way.
group-list access-list: Apply this
configuration to all multicast addresses
by default.
DES-7200(config)# no ip pim
cisco-register-checksum [group-list
access-list]
Remove the configuration.
6.3.19 Configuring the RP to Forward Multicast Packets to Downstream
Interfaces after Decapsulating Register Packets
To decapsulate the register packet and forward its multicast packets, execute the
following command in the global configuration mode.
Command Function
DES-7200(config)# ip pim
register-decapsulate-forward
Decapsulate the register packet and
forward its multicast packets
DES-7200(config)# no ip pim
register-decapsulate-forward
Remove the configuration.
In case of decapsulation and forwarding of many register packets, this function
incurs additional workload to CPU. So it is not recommended.
