Hi frankarmu,

You need to configure "Inter-AS Mode". Following document has all the information of all modes of MPLS L2 vpn with configuration examples.

Hi Spooster IT Services,

If i have the schema in attached, how can i configure a redundant connection with QinQ and MPLS Layer 2 VPN?

Sorry but i haven't a big experience regarding the configuration of redundant  L2 VPN, and in this case i need to configure the connection without the support of the provider :(

Thanks

just think about it like you have a long wire between sites.

You can do ethechannell for example.

The model doesn't allow to make an EtherChannell...maybe can I use the STP?

There is someone who has experience on this kind of configuration?

Usually to redundant the switch Layer 2 I use protocols like RSTP, LACP or IRF maybe it's the same also for this type of configuration or there is some warning to know?

Do your switches (sw1, sw2) support etherchannel?

[frankarmu]

No, because are also in two different location..
