Note that the above configuration specifies the VLAN interface through which Resilient
packets are sent, while all the VLAN interfaces can receive Resilient ARP packets.
2.3 Displaying Resilient ARP
After the above configuration, you can use the display command to display the
operation status, and verify the configuration effect through the displayed information.

2.4 Resilient ARP Configuration Example

I. Network requirements
There are four units in an IRF network: unit 1 to unit 4. Unit 1 and unit 3 connect to
another switch (Switch) through port convergence. If the connection between unit 1 and
unit 3 and the connection between unit 2 and unit 4 break off, there will be two Layer 3
switches with the same configuration in the network. In this case, problems occur in
packets forwarding between the fabric and the Switch. You can enable Resilient ARP
function for the fabric to avoid the problems. For security concerns, you need to enable
MD5 authentication function. The ports through which unit 3 and unit 4 connect to the
Switch belong to VLAN 2.
