Hello,
The length of an AS_CONFED_SEQUENCE is considered 0 (RFC 5065, 5.3 3)).
I think in your case, the tie break could be the router ID.

Hello!
I have an example of working BGP confederation, where, as I supose, the route

Both are IGP, both have equal preference, but the second one have shorter
as_path
