Configuring Ipv6 Ndp; Configuring A Static Neighbor Entry - 3Com S7906E Configuration Manual

The manually configured global unicast address takes precedence over the one automatically
generated. If a global unicast address has been automatically generated on an interface when you
manually configure another one with the same address prefix, the latter overwrites the previous
one. After that, the overwritten automatic global unicast address will not be restored even if the
manual one is removed. Instead, a new global unicast address will be automatically generated
again based on the address prefix information in the RA message that the interface receives for the
next time.
Executing the undo ipv6 address auto command removes all the automatically-generated global
unicast addresses from an interface. The automatically generated link-local address on the
interface can be removed only when no IPv6 site-local address or global unicast address exists,
and the ipv6 address auto link-local command is not configured.

Configuring a Static Neighbor Entry

The IPv6 address of a neighbor node can be resolved into a link-layer address dynamically through NS
and NA messages or through a manually configured static neighbor entry.
The device uniquely identifies a static neighbor entry according to the neighbor IPv6 address and the
local Layer 3 interface ID. Currently, there are two configuration methods:
Associate a neighbor IPv6 address and link-layer address with a Layer 3 interface.
Associate a neighbor IPv6 address and link-layer address with a port in a VLAN.
Follow these steps to configure a static neighbor entry:
To do...
Enter system view
Configure a static
neighbor entry
You can adopt either of the two methods above to configure a static neighbor entry.
After a static neighbor entry is configured by using the first method, the device needs to resolve the
corresponding Layer 2 port information of the VLAN interface.
If you adopt the second method, you should ensure that the corresponding VLAN interface exists
and that the Layer 2 port specified by port-type port-number belongs to the VLAN specified by
vlan-id. After a static neighbor entry is configured, the device relates the VLAN interface to the IPv6
address to uniquely identify a static neighbor entry.
Use the command...
system-view
ipv6 neighbor ipv6-address mac-address { vlan-id
port-type port-number | interface interface-type
interface-number }
