@Andy: Thanks for the pointer. I quickly gazed through RFC 8469. If I read it right, RFC 8469 tackles the problem in PW where the PW would confuse an ethernet packet with IP packet. Therefore, the RFC recommends to include CW in all PW. For this particular discussion, we want to document the impacts and hope the community can provide guidelines to transition the current applications that rely on persistent mac-addresses.

Best,
Yiu

Yiu,

Just FYI, this issue came up several years ago with regard to randomized MAC addresses in Ethernet frames contained in Ethernet pseudowires. Stewart and I wrote RFC 8469 to address the resulting effects that were encountered in the field.

Cheers,
Andy
