Hello,
I am eager with another hard project that consist in divide 2 buildings with L3. As you can see in the picture, both buildings is working together with L2 (all vlans are propagated through trunk interface between 6500 devices).
In this way when exists a L2 loop, this is propagated of all devices.
- The main issue to migrate to Level3 is that exists some devices that only works with multicast traffic and I don't know if multicast traffic of vlan can be migrated to L3.
-Somebody knows the best form to migrate to L3?

Thanks,
