Subject: [L2sm] Support of and interworking with legacy L2VPN types

Another issue on our list was whether we should support legacy VPN services like
ATMoMPLS, PPPoMPLS, and FRoMPLS.

At the interim we decided that while there is a lot of legacy deployment, there
are also four things to consider:

1. Legacy deployments are, erm, already deployed. They are static and don't need
more work for operational commissioning.

2. New deployments of legacy services are very, very rare.

3. Migration to new L2VPN services does happen, but is covered by the existing
module.

4. Interworking between legacy and new services is something so unusual that we
should not work on it.

As a result we determined to not support any form of ATM PVC.

Again, please shout if you have an issue with this.

Thanks,
Adrian
