VLAN IPv6 address does not ping on S5232F-ON
VLAN 100 is set as:
OS10(conf-if-vl-100)# ipv6 address 1::1/120
port-channel Interface 1/1/1:1 is using VLAN 100:
OS10(conf-if-eth1/1/1:1)# switchport trunk allowed vlan 100,200
From a Linux machine connected to that port-channel on VLAN 100, traceroute6 works (meaning it tells me 1::1, exists):
traceroute6 1::1
traceroute to 1::1 (1::1), 30 hops max, 80 byte packets
1 1::1 (1::1) 0.355 ms 0.186 ms 0.315 ms
If 1::1 is removed from VLAN 100, then the traceroute fails, thus we know it is there.
However, ping6 does not return:
ping6 -c 3 1::1
PING 1::1(1::1) 56 data bytes
--- 1::1 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2066ms
I am looking for a way to enable ping for the IPv6 VLAN interfaces.

This was caused by using a /120 and not enabling IPv6 extended prefix routes. See: https://www.dell.com/support/kbdoc/en-us/000210182/dell-emc-networking-os10-ipv6-extended-prefix-routes?lwp=rt

Hi,
Do you mind sharing the full configuration of the VLAN100, #show running-config interface VLAN 100 for us to check if there is any miss.
This is an example of the IPv6 config on interface: https://dell.to/3TSW1aN
