IXP peeps, why are you not offering high MTU VLAN option?
Biggest benefit would be if the transport network people run PPPoE and
other tunneled traffic over, would allow for whatever MTU needed to
carry unfragmented 1500 byte tunneled packets, so we could assure that
all hosts on the internet actually have 1500 IP MTU transparently.

How much traffic from DSLAM to service provider is currently being
exchanged across IXPs?

How much l2 vpn traffic is being exchanged across the public internet?
