Configuring A Customer-Side Port - HPE FlexNetwork 10500 Series Configuration Manual

Because Host A's IPv6 address is on the same subnet as Host B's, Host A directly sends an NS
message to obtain Host B's MAC address. However, Host B cannot receive the NS message
because they belong to different VLANs.
To solve this problem, enable local ND proxy on GigabitEthernet 1/0/2 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 a customer-side port

By default, the device associates an ND entry with routing information when the device learns an ND
entry. The ND entry provides the next hop information for routing. To save hardware resources, you
can use this command to specify a port that connects a user terminal as a customer-side port. The
device will not associate the routing information with the learned ND entries.
To configure a customer-side port:
Step
1. Enter system view.
2. Enter interface view.
