Hello everybody,
Was anybody able to set N1548 to work as a DHCPv6 relay? DHCPv4 works fine for me but it looks like DHCPv6 requests do not propagate through the switch. Here is my partial config of the switch:
ipv6 unicast-routing
ip routing
ip dhcp relay information option
ip helper-address 10.20.1.71
interface vlan 7
ip address 10.20.7.1 255.255.255.0
ip helper-address 10.20.1.71
ipv6 address 2001:db8:acad:2007::1/64
ipv6 enable
ipv6 dhcp relay destination 2001:db8:acad:2040::71
ip dhcp relay information option-insert
exit
interface vlan 20
ip address 10.20.20.3 255.255.255.0
ipv6 address 2001:db8:acad:2020::3/64
exit
ip default-gateway 10.20.20.1
ip dhcp snooping
ip dhcp snooping vlan 7
ipv6 dhcp snooping
ipv6 dhcp snooping vlan 7
interface Gi1/0/5
description "TEST"
spanning-tree portfast
spanning-tree guard root
switchport access vlan 7
exit
interface Gi1/0/9
ip dhcp snooping trust
ipv6 dhcp snooping trust
description "RT GE 0/0"
spanning-tree guard root
switchport mode trunk
switchport trunk allowed vlan 1,10,20,...
exit
ipv6 route ::/0 Vl20 fe80::1
DHCPv6 server is accessible:
SWITCH1#ping ipv6 2001:db8:acad:2040::71
Reply From 2001:db8:acad:2040::71 icmp_seq = 0. time= 1 msec.

Pinging 2001:db8:acad:2040::71 with 0 bytes of data:
Send count=4, Receive count=4 from 2001:db8:acad:2040::71
Average round trip time = 1.00 ms
Client is sending DHCPv6 solicits:
17:45:59.783117 IP6 fe80::bb65:e12f:4361:6396.546 > ff02::1:2.547: dhcp6 solicit
17:46:03.898007 IP6 fe80::bb65:e12f:4361:6396.546 > ff02::1:2.547: dhcp6 solicit
17:46:11.978889 IP6 fe80::bb65:e12f:4361:6396.546 > ff02::1:2.547: dhcp6 solicit
17:46:27.425233 IP6 fe80::bb65:e12f:4361:6396.546 > ff02::1:2.547: dhcp6 solicit
But no packets are coming out of the switch towards DHCPv6 server.
SLAAC is working fine and there is no problem with IPv6 connectivity in general.
Switch firmware is the latest: 6.3.3.8, but behaviour was the same on older versions.
Any input is highly appreciated.
Thanks,
Dmytro
