I have a note during a jncis-sp study I did...
"generated routes receive the next hop of the primary contributing route.
primary contributing route is the route with lowest preference of all the
contributing routes falling within the aggregate range of prefixes. if
there are multiple contributing routes with same preference, tie breaker is
LOWEST prefix number... NOT lowest prefix length."
Forgive me as I don't have much real-world experience with this topic, but
is this note above accurate ?
I'm wondering if he is getting lots of what appear to be ebgp learned
prefixes I'm thinking they would all be Preference 170, with all that being
tied at 170, would the tiebreaker go to the lowest prefix number ? like
18.104.22.168 or 22.214.171.124 or something low like that ?
