Hello guys,i am creating a network for a university project.I have created 3 sub interfaces on a router,and 1 vlan on each network.I can ping network
2001:4200:ACAD:1::/64 and
2001:4200:ACAD:2::/64 but not
2001:4200:ACAD:3::/64. I can only ping the interface on the router and from the 1 and 2 network.I can't ping from the pc connected to the switch on network 2001:4200:ACAD:3::/64.Help me please.

What about sh spanning-tree vlan 30 on switch 3?
10-24-2018 11:51 PM
HI there,
From the router what is the output of sh ipv6 neigh ?
Looking at your config it is not clear how the devices are connected. I can guess:
router| gi0/0 <---> gi0/1 |switch5| fa0/1 <---> PC
switch3 has trunk posts configured, but where is it connected?
cheers,
Seb.

From switch5 and the router what is the output of the sh spanning-tree vlan 30 ?
Also from switch3 what is the output of sh cdp neigh ?

Do you have routes to network 2001:4200:ACAD:1::/64, 2001:4200:ACAD:2::/64 and 2001:4200:ACAD:3::/64 on the L3 switch?

Could you provide a "show ipv6 route" from the L3 switch and the whole configuration. The limited configuration you provided is not sufficient.

I meant a "show ipv6 route" from the device where 2001:4200:ACAD:5::1 is configured. It would also be helpful to have the full configuration for that device.
