Looking over an IPE Appendix J, task 9 reads:
Your customer would like to have their VLANs remain consistent across your
network. You do not want other customers of yours to learn of their VLANs
from your network. You want to assign the VLANid of 22 to all frame that
will be "double-tagged"
The solution is provided as
vlan dot1q tag native
!
vlan 22
mtu 1504
!
interface FastEthernet0/2
switchport access vlan 22
switchport mode dot1q-tunnel
no ip address
l2protocol-tunnel shutdown-threshold stp 1024
l2protocol-tunnel shutdown-threshold vtp 1024
l2protocol-tunnel stp
l2protocol-tunnel vtp
no cdp enable
spanning-tree bpdufilter enable
I am curious as to why vlan 22 was set with an MTU of 1504.
Why was bpdufilter enabled? Does this prevent Vlan22 from being learned on
the network?
