Usage Guidelines

Usage Scenario

If you want a distributed gateway to learn ND packets only from hosts on the user side, run the ipv6 nd distribute-gateway enable command. After distributed gateway is enabled:

The gateway processes only ND packets received from user hosts and generates host routes.
The gateway deletes the ND packets learned from the network side and the hosts routes for the ND packets.

Prerequisites

IPv6 has been enabled in the VBDIF interface view using the ipv6 enable command.

Configuration Impact

After distributed gateway is enabled:

Tunnel-side static ND entries cannot be configured on the gateway.
In a distribution scenario, if multiple gateways use the same IPv6 address, the gateways do not report the address conflict.

Example

# Enable IPv6 distributed gateway on VBDIF 10.

<HUAWEI> system-view

[HUAWEI] interface vbdif 10

[HUAWEI-Vbdif10] ipv6 enable

[HUAWEI-Vbdif10] ipv6 nd distribute-gateway enable
