Hi, I followed the example in the documentation, but the PC which connects to the switch directly cannot get the default gateway from the switch.

Here I list the corresponding configuration:

dhcpv6 pool IPv6

address prefix 2001:xxxx:xxxx:11::/64

excluded-address 2001:xxxx:xxxx:11::1

dns-server 2001:yyyy:yyyyy::zzzz

 

interface Vlanif3

IPv6 enable

IPv6 address 2001:xxxx:xxxx:11::1/64

dhcpv6 server IPv6

 

Any suggestions?

Thanks

@sim_157 Hi,
Enable the RA message advertisement function to make the DHCPv6 client learn the default route destined for the IPv6 gateway through RA messages. Configure the M and O flags of the advertised RA messages to make the DHCPv6 client obtain an IPv6 address and other network parameters using DHCP.
[SwitchA-Vlanif100] undo ipv6 nd ra halt
[SwitchA-Vlanif100] ipv6 nd autoconfig managed-address-flag
[SwitchA-Vlanif100] ipv6 nd autoconfig other-flag
[SwitchA-Vlanif100] quit
