Thanks for working with me to clear my Discuss, which was: This Discuss ballot is probably more accurately a "Please clue in a TSV AD who is trying to pattern match and failing" ballot, and likely quick to resolve. But, I'm looking at this text: 4. Updates to RFC 4379 [RFC4379] specifies the use of the Router Alert Option in the IP header. Sections 4.3 and 4.5 of [RFC4379] are updated as follows: for every time in which the "Router Alert IP option" is used, the following text is appended: In case of an IPv4 header, the generic IPv4 Router Alert Option value 0x0 [RFC2113] SHOULD be used. In case of an IPv6 header, ^^^^^^ the IPv6 Router Alert Option value TBD1 allocated through this document for MPLS OAM MUST be used. When I click over to Section 4.3 of [RFC4379], I see this text: 4.3. Sending an MPLS Echo Request An MPLS echo request is a UDP packet. The IP header is set as follows: the source IP address is a routable address of the sender; the destination IP address is a (randomly chosen) IPv4 address from the range 127/8 or IPv6 address from the range 0:0:0:0:0:FFFF:127/104. The IP TTL is set to 1. The source UDP port is chosen by the sender; the destination UDP port is set to 3503 (assigned by IANA for MPLS echo requests). The Router Alert option MUST be set in the IP header. ^^^^ Could you help me understand whether this is really a MUST in Section 4.3 of [RFC4379] that is morphing into a SHOULD for IPv4 and remaining a MUST in IPv6? I have the same confusion in Section 4.5, but I'm betting the same answer applies.
