(0-246 octets) +-+-+-+-+-+-+-+-+-+-+-+- ``` It's somewhat unusual to have a header diagram that doesn't fill its rows and uses that space to instead define the field length for a second time (it's already defined by the horizontal space used, which is why there is bit count at the top.) ### Section 3.3.1, paragraph 4 ``` The remote AS number field has 4 octets. When only 2 octets are used for the AS number, the left (high-order) 2 octets MUST be set to 0. The remote AS number sub-TLV MUST be included when a router advertises an inter-AS TE link. ``` Would the higher-order octets not be zero anyway if the value is <= 0xffff? ### Section 3.3.4, paragraph 4 ``` If the originating node does not support IPv4, the IPv6 Local ASBR ID sub-TLV MUST be present in the inter-AS reachability TLV. Inter-AS reachability TLVs which have a Router ID of 0.0.0.0 and do NOT have the IPv6 Local ASBR ID sub-TLV present MUST be ignored. ``` NOT is not an RFC2119 term. ## Nits All comments below are about very minor potential issues that you may choose to address in some way - or ignore - as you see fit. Some were flagged by automated tools (via https://github.com/larseggert/ietf-reviewtool), so there will likely be some false positives. There is no need to let me know what you did with these suggestions. ### Grammar/style #### Section 5, paragraph 5 ``` this document. No additional acknowledgments are made for the new version ( ^^^^^^^^^^^^^^^ ``` Do not mix variants of the same word ("acknowledgment" and "acknowledgement") within a single text. ## Notes This review is in the ["IETF Comments" Markdown format][ICMF], You can use the [`ietf-comments` tool][ICT] to automatically convert this review into individual GitHub issues.
