Quick question, hope it's not too trivial:
When a router decides to forward a packet based on the longest match
principle, does this supersede other factors?
For example, if there is a route to network A via EIGRP, but a more specific
route available via OSPF, does it choose OSPF because of long
If the routes were equal (length), it would only have the eigrp route to
chose from, because that's the only route that would be in the table because
of the lower AD. The router would still have the route learned from OSPF in
it's osopf database, but it wouldn't enter it into the RIB unless it lo
i think it choose longest match,
what happend if this case between static route entry and eigrp route entry?
yes ,it choose longest.
but you know static route administrative distance is 1.

There are two separate processes involved here and it's
important to make a distinction between them. There is the
process by which the router builds the routing table and then
there is the route selection process.
When building the routing table, the router looks at the
various routes avail
I believe its distance to determine the protocol, then the longest
match after that...

excellent explanation, John.
to plug a source of study materials, Howard Berkowitz has an excellent paper
on how routers work, including the route determination process on
certification zone ( www.certificationzone.com )
per RFC 1812, all routers forward based on the longest match.

Looks like I should read it, since I was mistaken..:)

I would agree with you that it wouldn't load balance over paths with
differing ADs. However, theoretically, you could have a dynamic route
learned via a routing protocol (having a given AD) and you could add a
static route with the same length (i.e. /24) and purposely set the AD to
match the one
Related question to the above thread.
As discussed, each routing protocol will maintain its list of prefixes
that it knows about. A route selection process runs that considers the
routes from each routing process and puts the "best" into the routing
table. (best being defined by the route sel
