Configure Options on an IPv6 PIM Router

When IPv6 PIM is enabled globally, you can configure several PIM options for the router.

Enter global configuration mode.
```
device# configure terminal
```

Enter router configuration mode for the default VRF.

device(config)# ipv6 router pim
device(config-ipv6-router-pim-vrf-default-vrf)#

Run the following commands as needed.

For more information, including more examples, see the Extreme SLX-OS Command Reference.
1. Configure a device interface as a rendezvous point (RP).
```
rp-address 1234::22
```
2. Configure PIM Anycast RPs in multicast domains.
```
anycast-rp 1234::100 anycast-rp-peer-prefix-list
```
3. Configure a bootstrap router as a candidate RP to distribute RP information to other PIM-SM devices.
```
bsr-candidate interface ve 30 mask 126 priority 10
```
4. Configure a device as a candidate RP.
```
rp-candidate interface loopback 1
```
5. Enable Source-Specific Multicast (PIM-SSM) mode.
```
ssm-enable 
```
6. Configure the maximum size of the multicast cache.
```
max-mcache 500
```
7. Configure the frequency with which a device sends PIM hello messages to its neighbors.
```
hello-interval 50
```
8. Configure the length of time a PIM device waits for hello messages before considering a neighbor to be absent.
```
nbr-timeout 600
```
9. Configure the length of time a forwarding entry can remain unused before a device deletes it.
```
inactivity-timer 90
```
10. Configure the frequency with which PIM Join and Prune messages are sent.
```
message-interval 3600
```
11. Configure the length of time a PIM device waits to stop traffic after receiving a Prune message.
```
prune-wait 10
```
12. Configure sources to use the shared RP tree instead of the Shortest Path Tree.
```
spt-threshold infinity
```
13. Define the order in which unicast routes are selected from the routing tables during Reverse Path Forwarding (RPF) resolution.
```
route-precedence none priority-3 uc-non-default priority-2 uc-default priority-1
```
14. Enable multicast ECMP load sharing with dynamic rebalancing.
```
rpf ecmp rebalance
```
