Unable to ping router from PC with an IPv6 address in Cisco packet tracer

[Velqroh1994]

Hi all, 

I am trying to ping my router from a PC that has an ipv6 address. The pc's connected through a switch. I have set it to auto config for ipv6 addressing on the PC, it has gotten an address but unable to ping to the router.

Any suggestions? I have the necessary ipv6 enable, unicast-routing on. 

Note: the switch is connected through frm the gi0/1 interface

This is my router's config:

hostname Howick



enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0


no ip cef

ipv6 unicast-routing


no ipv6 cef



license udi pid CISCO1941/K9 sn FTX1524774Y





no ip domain-lookup


spanning-tree mode pvst



interface GigabitEthernet0/0

description This interface connects with the Howick VLAN Switch

no ip address

duplex auto

speed auto

ipv6 enable



interface GigabitEthernet0/0.15

encapsulation dot1Q 15

ip address 172.22.37.1 255.255.255.128


interface GigabitEthernet0/0.25

encapsulation dot1Q 25

ip address 172.22.37.129 255.255.255.192



interface GigabitEthernet0/0.86

encapsulation dot1Q 86

ip address 172.22.37.193 255.255.255.248

no ip address

ipv6 address 2001:DB8:AC4D:C::/64 eui-64

ipv6 enable

!

Any suggestions will help, thanks all.

Hi,

   Post your router configuration and the IPv6 address that the PC has.

Hi,

PC IPV6 is 2001:2222::10

Hi there,

From the router can you share the output from the following commands:

sh ipv6 int gi0/1

sh ipv6 neigh

Can you call share the PC interface configuration:

ip -6 address show <interface_name>

ifconfig

ipconfig

cheers,

Seb.

Hi,

Pls find attached..

Hi there,

Firstly, the output you provided is for a router with FastEthernet interfaces, not the GigabitEthernet interfaces specified in your original configuration.

Also you indicated that Gi0/1 was connected to the switch, however it is Fa0/0 which is configured with the correct IPv6 prefix.

Assuming the above are mistakes....

The IPV6 configuration looks good, but the empty neighbour table is not so great.

On the switch can you confirm that the switchports connected to the router Gi0/1 and the PC are on the same VLAN? Can you share the output of:

sh mac address

sh spanning-tree vlan <VLAN_ID_OF_SWITCHPORTS_CONNECTED_TO_GI0/1_AND_THE_PC>

cheers,

Seb.

Hi Seb,

Thanks for the reply.

Kindly note that the configuration which you are referring (GE) is posted by some other user. That's not my router configuration.

Thanks

ah ok, in which case please provide the output for the commands at the end of my message...
