BigIron RX(config)#ipv6 router pim
BigIron RX(config-ipv6-pim-router)# rp-candidate ethernet 2/2
Syntax: [no] rp-candidate ethernet <slot>/<portnum> | loopback <num> | ve <num> l pos
<slot>/<portnum>
The ethernet <slot>/<portnum> | loopback <num> | ve <num> parameter specifies the interface.
The device will advertise the specified interface’s IP address as a candidate RP.
• Enter ethernet <slot>/<portnum> for a physical interface (port).
• Enter ve <num> for a virtual interface.
• Enter loopback <num> for a loopback interface.
To add address ranges for which the device is a candidate RP, enter commands such as the
following.
BigIron RX(config)# ipv6 router pim
BigIron RX(config-ipv6-pim-router)# rp-candidate add ff02::200:2 64
Syntax: [no] rp-candidate add <group-ipv6 addr> <mask-bits>
You can change the group numbers for which the device is a candidate RP by deleting address
ranges. To delete a RP candidate, enter commands such as the following.
BigIron RX(config)# ipv6 router pim
BigIron RX(config-ipv6-pim-router)# rp-candidate delete ff02::200:1 128
Syntax: [no] rp-candidate delete <group-ipv6 addr> <mask-bits>
The usage of the <group-ipv6 addr> <mask-bits> parameter is the same as for the rp-candidate
add command.
Statically specifying the RP
Brocade recommends that you use the IPv6 PIM Sparse protocol’s RP election process so that a
backup RP can automatically take over if the active RP router becomes unavailable. However, if you
do not want the RP to be selected by the RP election process but instead you want to explicitly
identify the RP by its IPv6 address, use the rp-address command.
If you explicitly specify the RP, the device uses the specified RP for all group-to-RP mappings and
overrides the set of candidate RPs supplied by the BSR.
NOTE
Specify the same IP address as the RP on all PIM Sparse routers within the PIM Sparse domain.
Make sure the router is on the backbone or is otherwise well connected to the rest of the network.
To specify the IPv6 address of the RP, enter commands such as the following.
BigIron RX(config)# ipv6 router pim
BigIron RX(config-ipv6-pim-router)#rp-address 31::207
The command in the example above identifies the router interface at IPv6 address 31::207 as the
RP for the IPv6 PIM Sparse domain. The device will use the specified RP and ignore group-to-RP
mappings received from the BSR.
Syntax: [no] rp-address <ipv6-addr>
The <ipv6-addr> parameter specifies the IPv6 address of the RP.
