Hi Wim, Thanks again for raising the TTL concern associated with L3 forwarding for intra-subnet traffic.
To address that concern, I would add a section of TTL consideration as follows to my draft: "Some applications generate intra-subnet traffic with TTL set to 1. In such case, both ingress and egress PE routers MUST NOT decrement the TTL of such traffic even though such traffic is actually forwarded at layer3 in the Virtual Subnet solution. In other words, if the source and destination addresses of a given customer packet belong to the same subnet (i.e., the extended subnet), both ingress and egress PE routers MUST NOT decrement the TTL of such packet. Furthermore, the TTL of such packet MUST NOT be copied into the TTL of the transport tunnel and vice versa." I wonder whether it is OK now.
