I agree with Cal. Of course the lab topology is somewhat dictated by the
available equipment. If every router has a connection to an ethernet switch,
and at least 4 (maybe more) routers have a full mesh connection to a frame
relay switch -- this gives a lot of flexibility. The connection of
additional sync ports (pt-pt) and ISDN connections ,make the design less
flexible. These connections need more consideration.
Who is gathering input for the labs (content, format, etc.). I have some
that I have written and shared with a few people in Groupstudy. You might
want to look at them for format and/or content.

- Just to get the debate going on a "root" lab
topology. No flaming please.
While I applaud the efforts of those willing
to donate finished labs, I think that the goal
should be to build new - original lab materials
that use a "universal" topology, not one that
is biased towards one rack vendor or another.
I would advocate a scalable "universal" design
using what is known of the actual CCIE R/S lab.
My suggestion would be to build to:
LAN Connectivity WAN Connectivity
2621 Fa0/0 -> 3550#1
2621 Fa0/1 -> 3550#2 2621 S0/1 -> 2522
-----3550EMI----- ------2522------
2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6
2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
-----3550EMI-----
Dial Connectivity can be achieved using AUX
ports between routers in a back to back format.
Technologies such as ISDN, Voice, and ATM
which incur greater equipment cost per feature
can also be added.
Lab Designers can choose to use only a portion
of this equipment, or the full topology.
Lab Users would be able to acquire gear as
their budget allows, or rent as they need time.
