DES-7200 Configuration Guide Chapter 7 PIM-SMv6
Configuration
7-14
To enable the last hop device to transfer from the shared tree to the shortest path
tee, run the following command in the global configuration mode.
Command Function
DES-7200(config)# ipv6 pim
spt-threshold [group-list
ipv6_access-list]
If group-list is configured, the last
hop device of this multicast group is
enabled to transfer from the shared
tree to the shortest path tree.
Without group-list, all multicast
groups are permitted.
DES-7200(config)# no ipv6 pim
spt-threshold [group-list
ipv6_access-list]
Disable this function.
7.2.28 Configure the Specific Source multicast
This command enables the device to directly receive multicast packets from the
specific multicast source rather than the PR tree.
To configure the specific source multicast, run the following command in the
global configuration mode..
Command Function
DES-7200(config)# ipv6 pim ssm
{default |range ipv6_access-list]}
Configure the specific source
multicast,
232.0.0.1~232.255.255.255 by
default.
DES-7200(config)# no ipv6 pim ssm Remove the configuration.
7.2.29 Configure Static RP Preference
To configure the static RP’s priority higher than the one elected through BSR
mechanism, run the following command in the global configuration mode.
Command Function
DES-7200(config)# ipv6 pim
static-rp-preferred
Configure the static RP’s priority
higher than the one elected through
BSR mechanism.
DES-7200(config)# no ipv6 pim
static-rp-preferred
Remove the configuration.
7.2.30 Enable Embedded RP
Embedded RP is the special RP discovery mechanism for IPv6 PIM that uses its
IPv6 multicast address, from which the multicast router can directly resolve RP’s
address.
By default, embedded RP is enabled for the IPv6 multicast addresses of all
embedded RP addresses. To enable embedded RP for the IPv6 multicast
address of some embedded RP address, run this command in the global
configuration mode.
