What is the performance across such a tunnel when you start pumping data traffic across it ?
Say on a 3750 ? is it hard switched or soft switched ?
Would this be a solution to extend a vlan (possible server vlan) across an ip cloud ?
regards,
Geert

this mode is used in provider switched fabric to tunnel customer vlans across
provider's backbone. This way the provider does not have to worry about vlan
overlap etc etc. This mode by default does not tunnel your cdp/stp/vtp, which
need to be enabled separately with l2protocol-tunnel. Furthermore, starting
with 3750's I believe you can start tunnelling etherchannels which makes
things even more interesting. Although last time i dealt with my provider,
their 7600 could not handle it

Hello team,
Could anyone explain why I need this command. If I don't use it, things
seem to work just fine.
