DES-7200 Configuration Guide Chapter 7 PIM-SMv6
Configuration
7-7
7.2.9 Configure DR Priority
To configure DR priority, run the following command in the interface configuration
mode.
Command Function
DES-7200(config-if)# ipv6 pim
dr-priority priority-value
Configure DR priority in the range of
0 to 4294967294.
DES-7200(config-if)# no ipv6 pim
dr-priority priority-value
Restore DR priority to the default
value, namely 1.
7.2.10 Configure Static RP
In a smaller network, you can use PIM-SMv6 by configuring static RP. All devices
in the PIM-SMv6 domain should be configured with similar static RP for
consistent PIM-SMv6 multicast routes.
To configure static RP, run the following command in the global configuration
mode.
Command Function
DES-7200(config)# ipv6 pim
rp-address ipv6_rp-address
[ipv6_access-list]
Configure static RP.
DES-7200(config)# no ipv6 pim
rp-address ipv6_rp-address
[ipv6_access-list]
Remove the configuration.
Note that:
When BSR and static RP take effect simultaneously, static RP is preferred.
Static RP can be configured for many multicast groups (by using ACL) or all
multicast groups. However, one static RP can be configured only once.
If more than one IPv6 address is configured to be RP, the highest IPv6
address is adapted first.
Only the IPv6 addresses defined and permitted by ACL are valid multicast
groups. By default, all multicast groups are permitted.
After configuration, the source address of static RP is inserted in the tree
structure of the group range-based static RP group. Each group range-based
static RP group maintains a chain structure that lists static RP groups in the
descending order of IPv6 addresses. When a group range selects a RP, the
first element, or the highest IPv6 address is selected.
Deleting a static RP will delete it from all multicast groups and a new one is
selected from the static RP tree structure as static RP.
7.2.11 Configure Candidate BSR
Configuration of candidate BSR produces globally unique BSR in the PIM-SMv6
domain, which collects and distributes the RPs in the domain for the uniqueness
of RP mapping.
To configure candidate BSR, run the following command in the global
configuration mode.
