You replied to an earlier post:
I have some follow up questions about this if you don't mind.
According to your response of "extend l2 domain end to end" in relation to switch vs router across the Metro EVPL link, and that the router and subinterfaces will not do this,
Are you talking about STP, CDP?
I am not sure what you are talking about here, can you explain what I will be loosing in the router across the link rather than using the switch?
I understand the switches would trunk the VLANs as if there were in the same STP domain, is this what we would be loosing with the routers?
We have 6509 in our HW site and a 3750 stack in the DR site and I am wondering about QoS and encryption if we wanted to encrypt sensitive data across the link.
We would have more control with routers.
