That's not correct.
Actually, was fixating on the fact that he has ethernet WAN and last I checked IOS doesn't have unnumbered-to-ethernet capability (well not true, recently they introduced unnumbered SVI support, don't know if it actually works on anything else) Dave. -- David Freedman Group Network Engineering david.freedman@uk.clara.net Tel +44 (0) 20 7685 8000 Claranet Group 21 Southampton Row London - WC1B 5HA - UK http://www.claranet.com Company Registration: 3152737 - Place of registration: England All the information contained within this electronic message from Claranet Ltd is covered by the disclaimer at http://www.claranet.co.uk/disclaimer
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. Juergen Marenda.
