Configure Options on an IPv4 PIM Interface

When IPv4 PIM is enabled globally, you can configure PIM options for an interface (Ethernet, loopback, or VE).

Enter global configuration mode.
```
device# configure terminal
```
Enter device configuration mode.
```
device(config)# interface ethernet 0/1
```
Run the following commands as needed.
For more information, including examples, see the Extreme SLX-OS Command Reference.
1. Enable IPv4 PIM on an interface.
```
device(conf-if-eth-0/1)# ip pim-sparse
```
2. Specify the designated router (DR) priority of an IPv4 PIM interface.
```
device(conf-if-eth-0/1# ip pim dr-priority 200
```
3. Configure the Time to Live (TTL) threshold for an IPv4 PIM interface.
```
device(conf-if-eth-0/1# ip pim ttl-threshold 50
```
