Usage guidelines

Use ARP flood suppression to reduce ARP request broadcasts on the EVI network.

This feature snoops ARP replies on an EVI tunnel interface to populate the ARP flood suppression table with remote MAC addresses. If an ARP request has a matching entry, the edge device replies to the request on behalf of the remote-site host. If no match is found, the edge device floods the request to the EVI network.

When this feature is enabled, an EVI tunnel interface must send packets that contain a VLAN ID-based GRE key to remote edge devices. For the EVI tunnel interface to generate VLAN ID-based GRE keys, you must execute the gre key vlan-id command.

Examples

# Enable EVI ARP flood suppression on EVI tunnel interface Tunnel 101.

<Sysname> system-view
[Sysname] interface tunnel 101 mode evi
[Sysname-tunnel 101] evi arp-suppression enable
