Folks,
it works perfectly well with
!
pseudowire-class tortellini
encapsulation l2tpv3
ip local interface Vlan2
!...
!
where vlan2 is the wan interface on an 1812, for example.
You want to transport the real physical ports (fas0 or fas1 on the 1812)
to be able to transport vlan-tags, spanning-tree-bpd's, etc...
thru your l2tpv3 pseudowire,
so you will use one of the switch-ports for your "internet" Connection .
So there is no need to re-configure your working WAN connection.
