Hi Raszuk, I went through RFC7311 and my concern is different than RFC 7311. I have analyzed full BGP routing table (541,199 routes) with two tier 1 ISP multi-homing scenario and found nearly 50% of routes have equal AS-PATH length. In this analysis It was considered, there was no route policy applied to influence local preference. According to BGP best path selection algorithm, when AS-PATH lengths are equal, router breaks tie condition based on route internal logic. This does not grantee proper outgoing path selection.
Appreciate your concern on above analysis.
