Example: ELRP on Protocol-Based VLANs

For ELRP to detect loops on a protocol-based VLAN (other than the protocol any), you need to add the ethertype 0x00bb to the protocol.

1. Create VLANs:
   

   create vlan v1
   create vlan v2

2. Configure protocol filters:
   

   configure vlan v1 protocol IP
   configure vlan v2 protocol decnet

3. Add ports to the VLANs:
   

   configure vlan v1 add ports 1
   configure vlan v2 add ports 2

4. Enable ELRP on the created VLANs:
   

   enable elrp-client
   configure elrp-client periodic v1 ports all interval 5 seconds log
   configure elrp-client periodic v2 ports all interval 5 seconds log

5. Add the ethertype to the protocol:
   

   configure protocol IP add snap 0x00bb
   configure protocol decnet add snap 0x00bb

VLANs v1 and v2 can now detect the loop on their respective broadcast domains.
