Hi Renwei,

Yes, it's a local LER decision.....but the LER implementation has
consequences on downstream LSRs.

Do you agree that failing to MPLS encapsulate a IPv4 packet simply
because it has an IP option header may be a problem for the downstream
network?

If so, should we not promote a consistent implementation among vendor
LERs via an MPLS WG standard such that when an LER decides "whether to
push an MPLS label stack onto an IP packet, the determination is made
without considering any IP options that may be carried in the IP packet
header"??

Opposed.

This draft imposes a new requirement on LER. But the new requirement has
nothing to do with inter-op. Moreover, the new requirement is really a
matter of local implementation, and doesn't look really like a "MUST"
requirement.

Renwei
