To solve this problem, enable local ND proxy on GigabitEthernet 2/0/2 of the router so that the
router can forward messages between Host A and Host B.
Local ND proxy implements Layer 3 communication for two hosts in the following cases:
The two hosts connect to ports of the same device and the ports must be in different VLANs.
The two hosts connect to isolated Layer 2 ports in the same isolation group of a VLAN.
If super VLAN is used, the two hosts must belong to different sub VLANs.
If Private VLAN is used, the two hosts must belong to different secondary VLANs.
Configuration procedure
You can enable common ND proxy and local ND proxy in VLAN interface view, Layer 3 Ethernet
interface view, or Layer 3 Ethernet subinterface view.
To enable common ND proxy:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Enable common ND proxy.
To enable local ND proxy:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Enable local ND proxy.

Configuring IPv6 ND suppression

The ND suppression feature enables a device to directly answer ND requests by using ND
suppression entries. The device generates ND suppression entries based on dynamic ND entries
that it learns. This feature is typically configured on the PEs connected to base stations in an L2VPN
that provides access to an L3VPN network.
You can also configure the ND suppression push function to push ND suppression entries at
intervals by advertising NA messages.
Figure 88
shows a typical application scenario. ND suppression is enabled on the PE that connects
to the base station. The PE generates ND suppression entries for the base station, PE-agg 1, and
PE-agg 2, and it directly replies subsequent ND requests for these devices.
