Subject: Network study guides
Hi all,
Could somebody briefly clarify how to summarize two IP addresses.
I have the Todd Lammle ACRC exam notes book and it just ain't clear!
Also, has anyone used the study guides and practice exams from Network study
guides (www.networkstudyguides.com) I'm particularly interested in them as
they have info out on the new CCNP routing 2 exam - material on this seems
rare at the moment. Any opinions welcome. Thanks in advance
David Welch
