DES-7200 Configuration Guide Chapter 7 PIM-SMv6
Configuration
7-12
DES-7200(config)# ipv6 pim
register-source
{ipv6_local_address | interface-type
interface-number}
Configure the source address of
registration packets.
DES-7200(config)# no ipv6 pim
register-source
Use the RPF’s interface address as the
source address of registration packets.
7.2.23 Configure the Suppression Time of Registration Packets
When the receiver does not receive the data packets destined to a multicast
group from RP (namely RP does not serve this multicast group) or RP begins to
receive multicast packets from the multicast source, RP sends the registration
stop message to the DR on the multicast source side. Upon receiving this
message, DR stops sending the registration packets encapsulated with multicast
packets and transfers into the register suppression state.
During registration suppression, DR sends null registration packets, namely
registration packets not encapsulated with multicast packets), to DR, indicating
that the multicast source is still active. Probe time refers to the period that DR is
allowed to send null registration packets before the registration suppression state
is timed out. When registration suppression is timed out, DR starts to send
registration packets. The smaller registration suppression timeout means the
higher frequency that RP receives multicast packets; the larger timeout means
the higher delay for a receiver to join a multicast group.
Running this command on DR will change the registration packet suppression
time defined on DR.
To configure the registration packet suppression time, run this command in the
global configuration mode.
Command Function
DES-7200(config)# ipv6 pim
register-suppression seconds
Configure registration packet
suppression time.
Seconds: in the range 1 to 65535s
DES-7200(config)# no ipv6 pim
register-suppression
Restore the setting to the default
value.
7.2.24 Configure the Probe Time of Null Registration Packet
The DR can send the null registration message to the RP in a period before the
registration suppression time expires. This period is call probe time, 5 seconds by
default
To configure the probe time of null registration packet, run the following command
in the global configuration mode.
Command Function
DES-7200(config)# ipv6 pim
probe-interval interval-seconds
Configure the probe time of null
registration packet.
interval-seconds: in the range 1 to
65535 seconds
DES-7200(config)# no ipv6 pim
probe-interval
Restore the setting to the default
value.
