Title : Requirements for Label Edge Router Forwarding of IPv4 Option Packets
Author(s) : W. Jaeger, et al.
Filename : draft-ietf-mpls-ip-options-05.txt
Pages : 10

This document specifies how Label Edge Routers (LER) should behave
when determining whether to MPLS encapsulate an IP packet with header
options. Lack of a formal standard has resulted in different LER
forwarding behaviors for IP packets with header options despite being
associated with a prefix-based Forwarding Equivalence Class (FEC).
IP option packets that belong to a prefix-based FEC yet are forwarded
into an IP/MPLS network without being MPLS-encapsulated present a
security risk against the MPLS infrastructure. Further, LERs that
are unable to MPLS encapsulate IP packets with header options cannot
operate in certain MPLS environments. While this newly defined LER
behavior is mandatory to implement, it is optional to invoke.
