Hey everyone,
I'm fighting my way through the sections in the subject and I'm baffled by
the behavior I'm seeing in EIGRPv6. Can anyone help to to understand how
these two routes are coming in with very different ADs and yet R6 is
calculating the same FD for them? Both receiving interfaces have the same
values for metric calculation, and yet both routes end up with the same FD
even though one comes in with 230400 less on the AD.
R6#sh ipv6 eigrp top 2001:100::5/128
IPv6-EIGRP (AS 100): Topology entry for 2001:100::5/128
