Have a production campus LAN network primarily running with 3508Gs and
3524XL data switches with gigabit fiber uplinks. All switches are
currently running ISL Vlan trunking between the uplink ports. There's
also a 2620 router running ISL fastethernet subinterfaces configured
with encapsulation IS

Not for the window it's receiving, but for a previous window.

The DR is elected first by highest priority, the tie breaker is highest RID.
Then the process is repeated for the BDR.

My understanding is that if the DR goes down then the BDR is promoted to DR
and an election is held for the new BDR. This means
I agree with Dre

Additionally, gigabit need not run full duplex. Specifically, look into the
Gigastack modules for switches. They can run full duplex when there are
only two switches in the stack, but the moment you add a third switch, it
becomes a shared bus, and all interfaces are forced to half-duplex
operatio
This would be when you are using the Gigastack options? Isn't normal
operation of Gigabit is FULL DUPLEX. My thoughts were that collisions on
Gigabit were bug/hardware problems, not flow control, normal, or
representation of giants.

no discard route internal (does not install the Null0 route in routing
table)

I think your thinking way too hard about this;) A loobback is
nothing more than a logical interface as opposed to a physical
interface. As far as the routing process is concerned it's just another
interface. Don't know how to articulate it any further.

You gentlemen have pointed out some good uses for loopback interfaces.
However, my dilema still remains that I have yet to have somebody solidly
explain loopback interfaces in a way that my simple mind can understand. I

Thanks Alex but when your routers are going back to back LMIs are
turned off with the no keepalive command. I believe because a Frame
switch is not involved in creating the PVC.
In any case I updated the IOS image to 12.3.1a on both routers and
the connection comes back up without any issues
Hi everybody
The case .. OSPF summary address with Null 0
In all the case studies for CCIE R & S we told don't use static routes! .
While we need to have a static route to Null 0 with address summarization.

What we do? What is the best?
Any idea???
I am reading the CCNP/CCIP BSCI Study Guide by Todd Lammle from Sybex. In
the OSPF section under the discussion of DR and BDR (page 171) he says that
the BDR is chosen first and that the DR is chosen from the reaming list.
That seems illogical and backwards. Can someone please confirm or deny a

Not sure what filtering capabilities you have on the switch,

Hi all,
I am taking the new BSCI test next monday, if anyone has taken it I am
looking for some suggestions to know what is heavily covered on the exam.
Thanks in advance

Fast and direct graphs? Use the sysadmin way.
Between router and hub/switch put a hub/laptop in between (or use span
ofcourse) with sniffer software running.. for a few days.
First check after a few hours that you see what you want to see.
It'll give you anything you need in gui and more.
