334
Default level
2: System level
Parameters
None
Description
Use the ipv6 nd detection enable command to enable ND detection in a VLAN to check ND packets for
source spoofing.
Use the undo ipv6 nd detection enable command to disable ND detection.
By default, ND detection is disabled.
Examples
# Enable ND detection in VLAN 10.
<Sysname> system-view
[Sysname] vlan 10

Default level
2: System level
Parameters
None
Description
Use the ipv6 nd detection trust command to configure a port as an ND-trusted port.
Use the undo ipv6 nd detection trust command to configure a port as an ND-untrusted port.
By default, a port is ND-untrusted. In an ND detection-enabled VLAN, ports are assigned two roles: ND-
trusted and ND-untrusted.
 On an ND-trusted port, the ND detection function does not check ND packets for address spoofing.
 On an ND-untrusted port, RA and RR messages are considered illegal and discarded directly; all
other ND packets in the VLAN are checked for source spoofing.
Examples
# Configure Layer 2 interface GigabitEthernet1/0/1 as an ND-trusted port.
<Sysname> system-view
[Sysname] interface GigabitEthernet 1/0/1
[Sysname-GigabitEthernet1/0/1] ipv6 nd detection trust
# Configure interface Bridge-Aggregation 1 as an ND-trusted port.
