• Router mode - When a policy with device role as router is applied on an interface, all the RA packets are validated based on the configuration information in the policy. Similarly, you can also apply this mode over any specific VLAN and the validation is performed only for that particular VLAN RA packets. To configure the IPv6 RA guard, use the following Dell Networking OS commands. clear ipv6 neighbors Delete all entries in the IPv6 neighbor discovery cache or neighbors of a specific interface. Static entries are not removed using this command. C9000 Series Syntax Parameters clear ipv6 neighbors [ipv6 address] | interface interface | vrf vrf name] ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x format to remove a specific IPv6 neighbor. NOTE: The :: notation specifies successive hexadecimal fields of zero. vrf vrf-name (OPTIONAL) Enter the keyword vrf followed by the name of the VRF to clear the neighbor corresponding to that VRF. NOTE: If you do not specify this option, the neighbors in the default VRF are cleared. interface interface To remove all neighbor entries learned on a specific interface, enter the keyword interface then the interface type and slot/port or number information of the interface: Enter one of the following keywords with slot/port or number to clear information about the IPv6 neighbors learned on the specified interface: • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information • For a 10-Gigabit Ethernet interface, enter the keyword tengigabitethernet then the slot/port information. • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information. • For a port-channel interface, enter the keyword portchannel with a port-channel number. The range of port-channel numbers is from 1 to 128. • For a VLAN interface, enter the keywordvlan then a number from 1 to 4094. • For a tunnel interface, enter the keyword tunnel.
