Configuration Guide Configuring IPv6
Enable IPv6 redirection on interface GigabitEthernet 0/0.
Ruijie(config-if-GigabitEthernet 0/0)#ipv6 redirects
Run the show ipv6 interface command to check whether the configuration takes effect.
ICMP redirects are enabled
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
ND retransmit interval is 1000 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND router advertisements are sent every 200 seconds<160--240>
ND router advertisements live for 1800 seconds
 Configuring IPv6 DAD
Configure the interface to send three consecutive NS packets during DAD.
Ruijie(config-if-GigabitEthernet 0/0)# ipv6 nd dad attempts 3
Run the show ipv6 interface command to check whether the configuration takes effect.
Ruijie#show ipv6 interface gigabitEthernet 0/0

 Configuring Prefix Information in an RA Packet
Add a prefix 1234::/64 to interface GigabitEthernet 0/0.
Ruijie(config-if-GigabitEthernet 0/0)#ipv6 nd prefix 1234::/6
Run the show ipv6 interface command to check whether the configuration takes effect.
Ruijie#show ipv6 interface gigabitEthernet 0/0 ra-info
