Depending on the content of the headers, this address can be "injected" into the flow of the email. This is very easy to do. The important thing to look at regarding the headers from such an email are the last few transactions I would suspect that the first few lines read IPs that are familiar

MPLS as a protection mechanism

I read the thread on NANOG about MPLS in Metro Networks and the replies danced around this issue but didn't address it directly. I'd like to know if anyone is/is considering using MPLS as a Layer 1 or Layer 2 protection mechanism, whether alone or in combination with other protection mechanisms.

layer 3 switch debate

IP Community: When designing an all IP network requiring mostly Ethernet interfaces, the logical conclusion is to specify layer 3 switches (instead of routers). The cost per port and functionality requirements make a layer 3 switch the perfect choice. However, the rule of thumb in the IP comm

Thanks to all who have responding with information from their network vantage point. It does indeed seem to be an IGP or blackholing issue inside of Sprint. In the interim I made an advertising change to hopefully minimize the impact until I hear from someone at Sprint as to what the issue
