BGP Path Selection and Confederations

If I am using confederations, how does the as_confed_sequence affect path selection?

In particular:

1. Is the as_confed_sequence computed as part of the as-path length?

2. If I have the following four routes as, what is the order of preference?

a. 999

b. (65001) 999

c. (65002 65001) 999

d. (65003 65002 65001) 999

Re: BGP Path Selection and Confederations

1. Is the as_confed_sequences computed as part of the

as-path length?

as_confed_sequence has a length of

zero in as-path length calcuation.

2. If I have the following four routes as, what is the order of preference?

In term of as-path attribute, they

all have the same length.
