completion for the RFC6396 (MRT Routing Information Export Format) concerning the RIB entry format


Vote count:

The RFC6396 specifies the header for RIB-entry mrt-records like this:



0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

| Attribute Length |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| BGP Attributes... (variable)
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+


But the textual explanation (link) does not specify how and in which order the BGP Attributes appear. I assume that they mean path attributes of the BGP-4 standard. As a result I am not sure how they will be represented as no further information is provided, and no link to a section of the BGP-4 standard is provided leading me to second guess my assumption.


Therefore I want to know: How and in which order are the BGP attributes to be represented to be consistent with RFC6396 (Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format)?
