PowerConnect 7024 - IPv6 route issue

Hi,

Where is the server pointing for its default gateway, the 7024 or the sonicwall? Is IP routing enabled on the 7024? What version is the firmware on the switch at? How is the interface between the sonicwall and the 7024 configured? It seems like that is the location of the problem. Is it set as a trunk port or a general port? Is it set to carry both VLAN 1 and 100?

Hi,

The server gateway is 2403:b100:1012:1::1 (VLAN 1 in the 7024).

!Current Configuration:
!System Description "PowerConnect 7024, 5.0.1.3, VxWorks 6.6"
!System Software Version 5.0.1.3
!System Operational Mode "Normal"

ip routing

interface vlan 100
ipv6 address 2403:B100:1012::4/64

interface vlan 1
ipv6 address 2403:B100:1012:1::1/64

ipv6 route ::/0 2403:B100:1012::1

interface Gi2/0/24
description sonicwall_firewall
spanning-tree portfast
switchport access vlan 100
exit

How is the routing configured? Is there a static route or are you using OSPF to send the routing information from the switch to the router? Is there a reason why you are using access mode on Gi22/0/24? Trunk mode would pass tagged VLANs between the router and switch, access mode transmits untagged on VLAN 100 in your configuration.

Miss out some switch configuration provide to you. Here is the complete one.

Network diagram:

Sonicwall firewall(VLAN 100) <> 7024 L3 switch <> 5548 L2 switch(VLAN 1) <> server(VLAN 1)

I want set up dual stack network. IPv4 is running well. Only IPv6 encounter route issue. I have reported to Sonicwall support, he said configuration in firewall in fine. We also did few ping tests and capture ping packet between sonicwall and server. The result is we can see sending ping packet but not response from destination.   

If it is working on IPv4 and not on IPv6 we are going to want to update the firmware on the switches as there were some changes that may resolve the issue.

Problem solved after add ipv6 unicast-routing.
