You can use the following command to configure through which VLAN interface the 
resilient ARP packet is sent. The system provides a default VLAN interface to send 
resilient ARP packets.

Perform the following configuration in System View.

By default, the system sends resilient ARP packets through VLAN interface 1. 

Note that you only specify resilient ARP packet-sending VLAN interfaces, and any 
VLAN interface can receive resilient ARP packets. 

After the above configurations are completed, you can enter the 

 command 

in any view to view the running of resilient ARP function and to further check 
configuration results. 

You can also enter the 

 command in User View to debug the resilient ARP 

function. 

There are four units, numbered respectively Unit 1 through Unit 4, in the XRN 
network. Unit 1 and Unit 3 are connected to the Switch in link aggregation mode. 
Resilient ARP runs on the XRN fabric to avoid packet forwarding problems between 
the Switch and fabric when the network has two Layer 3 units, if the links between 
unit 1 and unit 3, between unit 2 and unit 4 are disconnected. MD5 authentication is 
enabled for the sake of security. The ports of Unit 1 and Unit 3, connecting the 
Switch, belong to VLAN 2.
