ISDN:TIP
1.After making your initial ISDN configs, use the "isdn test call interface
bri (DN#)" command to verify that your interface working properly.
Also, use the "isdn test call disconnect interface bri all" instead of
"clear int bri 0/0". The latter command can cause problems with the isdn
switch that may cause you problem later on.
2. If your using dialer interfaces make sure to use either ppp or dialer
caller to identify the calling party(by name or number).
Shootin from the hip here, so forgive the typos...

Subject: Lab Tips
> Hi all,
>
> I've created a "Lab Tips" file of small items - factoids, reminders,
> suggestions, etc, I tend to forget. This is something I can refer to
> constantly when I'm doing practice labs or just have a few minutes to
spare.
>
> Here's a snippet from my Tips file.
>
> BGP
> Hard code router-id
> Don't use loopbacks for ibgp peering unless explicitly required
> Look for nei ... next-hop-self requirement especially on F/R hub and
> ethernets
> Disable bgp client to client reflection when clients are fully meshed
> Turn off auto-sum & sync unless explicitly required
> Reset BGP sessions using hard reset rather than soft reset.
> Know how to config nei xxxx local-as in combo with RR.
> Know all ways to config dampening
>
> I'm sharing this with GS because I suspect many candidates might also have
> something like this. And, I thought that with all the great brain power
> among GS subscribers we could all help each other by adding tips to such a
> file.

> Here's my definition of what makes for a good tip.

> 1) A tip may not in any way violate the NDA

For

the
> "fram map clns <dlci> broadcast" statement. For me, this is a good tip
> because I personally don't practice ISIS that often and I seem to almost
> always forget that command.

> 3) A good tip must be short and clear because the whole idea behind this

> 4) A good tip must should not waste time going into the "why" of the fact
or

the

> 5) A good tip for one person might not be at all useful to someone else.
We

> time the BGP tips section may include 30 items and while I doubt all 30
> items will be useful to all people, I'm sure that 5 or 10 or 15 of the
tips
> will be useful to many people - just that it won't be the same 5 or 10 or
15
> tips.
>
> 6) A good tip must be potentially relevant to a ccie R&S candidate.
> Therefore, I ask that Off Topic comments be submitted elsewhere - Let's
keep
> posts with the subject "Lab Tips" focus on just that.
>
> It's my hope that over time, with the input of a lots of people here, this
> lab tips file will grow to include tips that cover every topic potentially
> on the R&S lab exam. And, that as a result, we can each add the most
> personally valuable tips from this group effort to our own lab tips file.

> Right now, my tips file has no entries for voice. So, I'd like to start
off

submit
