I'm sorry, I've just made a mistake and you were correct: in the example you
gave just EIGRP route would get to the routing table. If we had the
opposite, with a more specific route learned by EIGRP and another less
specific route learned by OSPF, then we would have both on the routing table
and the longest match rule would act.
So, the rule is: the admin distance is used by the router to choose which
route to put on the table. Since routes are already there, then the longest
match will count.
My apologies,

I don't think this is correct: If you have a route learned by EIGRP and a
more specific (longer match) route learned by OSPF, both will go to the
routing table, by the same reason that you still have a route learned by
any routing protocol on the table even if you have a more specific route
staticaly defined (which has a lower administrative distance). With both
routes int the routing table, then the longest match will count...

In a nut shell yes and no. i.e.
Admin distance is the winner by means that the lower the admin distance the
better, so a route learned from EIGRP will get into the routing table
despite having a longer match route which was learned from say OSPF. BUT if
you have two routes learned from the same admin distance then the longest
match ALWAYS wins.
Basically once the route is in the routing table then the longest match is
the outmost winner.

Does the longest match rule always override administrative distance??
