Cisco2960:

interface Vlan6

no ip address

ipv6 address 2001:DB8:0:22::3/64

ipv6 unicast-routing

Cisco3560:

no ip address

When I connected 3560 and 3560 with ipv6, it can ping, but it failed when I connect 3560 and 2960. Why?

[dakai.yan@dallasgrp.com]

Today I config the same configuration on both real 3560 and 2960. And they can't ping mutually.

Catalyst3560：

interface GigabitEthernet0/1

 switchport access vlan 21

interface Vlan21

 ip address 172.16.0.1 255.255.255.248

电脑172.16.0.5/29，可以ping通。

interface Vlan8

 no ip address

 ipv6 address 2001::1/64

 ipv6 enable

interface GigabitEthernet0/2

 switchport access vlan 8

电脑设置2001::2/64，可以ping通。可以telnet 2001::1

Catalyst2960：同AP交换机信息。

interface GigabitEthernet1/0/1

 switchport access vlan 8

interface Vlan8

 ip address 172.16.0.3 255.255.255.248

interface GigabitEthernet1/0/2

 switchport access vlan 5

interface Vlan5

 no ip address

 ipv6 address 2001::3/64

 ipv6 enable

电脑设置2001::2/64，可以ping通，可以telnet 2001::3

can you post show run from all device again -to cross check

[dakai.yan@dallasgrp.com]

Yes, on the physical switch both 2960 and 3560. But can't ping mutually.

Thanks. I will try.
