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.
