Enabling Nd Proxy - HPE 3100 Configuration Manual

If a corresponding NA message is received (the source IPv6 address, source MAC address,
receiving port, and source VLAN are consistent with those of the existing entry), the device
updates the aging time of the existing entry.
If no corresponding NA message is received within one second after the DAD NS message
is sent out, the device removes the entry when the timer expires.
Configuration procedure
To configure ND snooping:
Step
1. Enter system view.
2. Configure ND snooping.
3. Enter VLAN view.
4. Enable ND snooping.
5. Return to system view.
6. Enter Layer 2 Ethernet
port view/Layer 2
aggregate interface view.
7. Configure the maximum
number of ND snooping
entries the interface can
learn.
8. Configure the interface as
an uplink interface and
disable it from learning
ND snooping entries.

Enabling ND proxy

ND proxy supports the NS and NA messages only.
Introduction
If a host sends an NS message requesting the hardware address of another host that is isolated from
the sending host at Layer 2, the device between the hosts must be able to forward the NS message
to allow Layer 3 communication between the two hosts. This process is achieved by ND proxy.
Depending on application scenarios, ND proxy falls into common ND proxy and local ND proxy.

Common ND proxy
Command
system-view
•
Enable ND snooping based on global
unicast addresses (the devices use
DAD NS messages containing global
unicast addresses to create ND
snooping entries):
ipv6 nd snooping enable global
•
Enable ND snooping based on link
local addresses (the devices use DAD
NS messages containing link local
addresses to create ND snooping
entries):
ipv6 nd snooping enable link-local
vlan vlan-id
ipv6 nd snooping enable

By default, ND snooping is
disabled.

Optional.
By default, the number of
ND snooping entries an
interface can learn is
unlimited.

By default, when ND
snooping is enabled on the
device, an interface is
allowed to learn ND
snooping entries.
