An Admin Distance of "5" as it pertains to EIGRP
indicates that
Manual-Summarization has taken place.
That is one of the nice features of EIGRP over let's say
OSPF. EIGRP allows
you to summarize anywhere; not just at borders of the
network.

[7:109421]
I just checked, and 5 is an EIGRP summary route, so that is
correct. And
there's me trying to be a know it all. I must admit I
probably don't
know the answer to this one, and I'm over to the pub
shortly for pints
as its a bank holiday over here, so probably no time to look
it up.
I'd say if the other routers are learning the summaries
you
desire, surely everything is okay?
I wonder if the admin distance of 5 is something to do with
auto-summarization at classful boundaries rather than manual
summarization?
Let me know how you get on. I may have a look at this
tomorrow.
Cheers,
David.
