ipv6 nd proxy inter-access-vlan enable

Function

The ipv6 nd proxy inter-access-vlan enable command enables inter-VLAN ND proxy on a VLANIF interface.

The undo ipv6 nd proxy inter-access-vlan enable command disables inter-VLAN ND proxy on a VLANIF interface.

By default, inter-VLAN ND proxy is disabled.

Usage Guidelines

Application Scenario

In a VLAN aggregation scenario on an IPv6 network, if hosts in different sub-VLANs need to communicate at Layer 3, enable inter-VLAN ND proxy on the VLANIF interface corresponding to the super-VLAN. In this way, all sub-VLANs in the super-VLAN are reachable to each other.

Prerequisites

In the VLANIF interface view:

Run the ipv6 enable command to enable the IPv6 function.
Run the ipv6 address command to configure an IPv6 address for the interface. The IPv6 address must be in the same network segment as the IPv6 addresses of all sub-VLAN hosts.

Example

# Configure inter-VLAN ND proxy on VLANIF 30, the VLANIF interface corresponding to super-VLAN 30.

<HUAWEI> system-view
[HUAWEI] interface vlanif 30
[HUAWEI-Vlanif30] ipv6 enable
[HUAWEI-Vlanif30] ipv6 address fc00::1/64
[HUAWEI-Vlanif30] ipv6 nd proxy inter-access-vlan enable
