DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
457
47-11 ip pim old-register-checksum
This command is used to specify for which RP, the switch should calculate checksum include the data portion or not
when transmitting and receiving register messages. To restore the default setting, use no form of this command.
ip pim old-register-checksum rp-address RP-ADDRESS
no ip pim old-register-checksum rp-address RP-ADDRESS
Parameters
47-12 ip pim ssm
This command is used to configure the SSM multicast group address range. Use the no form of the command to
disable PIM SSM.
Example
This example shows how to configure the PIM candidate BSR priority to be 10 and
hash mask length to be 32.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#ip pim bsr-candidate vlan2 hash-mask-length 32 priority 10
DXS-3600-32S(config)#
Example
This example shows how to disable the function of BSR in ‘vlan2’.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#no ip pim bsr-candidate vlan2
DXS-3600-32S(config)#
RP-ADDRESS Specifies that the RP will expect to receive a register packet in which the checksum
will include the data portion or not.
Default
The checksum in the register message to any RP doesn’t include the data portion.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 8. (EI Mode Only Command)
Usage Guideline
This command is used to decide the checksum in register packet will include the
data portion or not. As defined in RFC 4601, the checksum for Registers is done only
on the first 8 bytes of the packet, including the PIM header and the next 4 bytes,
excluding the data packet portion. Some earlier PIM-SM routers calculate checksum
for register packet including data portion. This configuration makes our routers
communicate with those earlier routers smoothly. The default setting is not including
data portion.
To verify your configuration, use command show ip pim.
Example
This example shows how to configure the checksum to include data for RP
172.18.63.2
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#ip pim old-register-checksum rp-address 172.18.63.2
DXS-3600-32S(config)#
Example
This example shows how to delete the checksum to include RP 172.18.63.2
DXS-3600-32S#configure terminal
DXS-3600-32S(config)#no ip pim old-register-checksum rp-address 172.18.63.2
DXS-3600-32S(config)#
