Hello All: As more and more providers move towards Ethernet as a common connection type in Data Centers, Metro Areas and beyond, I am curious to know what people are using for Best Practices regarding customer connectivity into your Layer 2 networks. Most importantly, how do you handle customers that want redundant Ethernet connections? I've put together the following list of questions and I'd be happy to summarize to the list if there's any interest. Also, if individuals have any other pertinent questions they feel I've left out, please don't hesitate to let me know. 1) Do you allow redundant Ethernet (Layer 2) connections into your network? 2) Do you allow customers to connect at Layer 2? And, if so: a) What, if any, port-based limitations on protocols? (Root Guard, BPUD-filtering, etc.?) b) What, if any, MAC restrictions do you have on the ports? 3) Do you allow customers to transmit HSRP/VRRP/GLBP state information across your Layer 2 infrastructure? 4) Do you require Layer 3 terminations for customers with redundant connections? 5) Do you provide OSPF "peering" to customers with redundant connections? 6) Do you provide BGP peering to customers with redundant connections?
