Configuring A Customer-Side Port; Configuring Path Mtu Discovery; Configuring The Interface Mtu - HP 6125XLG Layer 3-Ip Services Configuration Manual

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 so the device will
not associate the routing information with the learned ND entries.
To configure a customer-side port:
Step
Enter system view.
1.
2. Create a VLAN interface and
enter its view.
3. Specify the VLAN interface as a
customer-side port.

Configuring path MTU discovery

Configuring the interface MTU

IPv6 routers do not support packet fragmentation. If the size of a packet exceeds the MTU of the output
interface, the router discards the packet and sends a Packet Too Big message to the source host. The
