Group...
I was asking a lot of BGP questions on here until I bought this book
Internet Routing Architectures (Cisco Press: ISBN1-57870-233-X, by Sam
Halabi) - the second edition just came out, and it is one of the best Cisco
press books I have read, if not the best. It really tackles the complex
Here is my dilemna: I could probably answer most questions on CCNP, CCIE
written, etc. exams on subnetting, but the most important thing seems to be
real-world experience. I'm mainly looking for more info on the following
topics:
- /30 for wan links, when/where to use
- if you have a /20 (exampl

Cisco recommends using:
ip rtp 16384 16383 bandwidth
for RTP. Out of the range 16384-32767 that VoIP uses, how does it use the
port numbers? What ports are used for fax? I have looked on Cisco's
website and I have not been able to find any good information on this.
Also, these are UDP ports.
Are there any mailing lists that focus primarily on Cisco VoIP, not VoIP in
general?
Thanks,
John

If I add a loopback interface to a router, when will the router take it as
the router ID? Here's a scenario:
Serial2/1 is the current router ID: 209.1.1.1
I add Loopback0, which is 10.0.0.1
Shouldn't the router take this as its router ID? When does this happen?

Is anybody out there on the bleeding edge, running IOSes like 12.1(3)T and
12.1(3a)XI2? Just wanted to share some experiences for off-list
discussion. I've become sort of the IOS evangelist ;) around here and I'm
evaluating and testing all the new features for MPLS TE, VoIP, T.37/T.38,
etc. etc

Some things that might help:
1. Are you using CODEC like G.729 that works at an
8Kbps bit rate? If not, you'll be hating life.
2. Bandwidth at full rate & Multilink PPP
(MLPPP) or FRF.12 will still be 17.2kbps.
3. You need QoS, even if you can burst to port
speed at 56kbps.
4. Consider LLQ
Does anyone know where I can find good whitepapers or configuration examples
of BGP in multi-homed environments? ARIN won't give out anything less than
a /21, but some providers won't advertise networks unless the IPs belong to
you. Just another situation where politics are as much of a part of

According to this, you have to have IOS release 12.0(7)XK or higher for the

I want to have a spare flash card for emergency
usage in my lab, has anyone tried using a standard PC Card flash memory,
such as a Kingston CompactFlash card?
Kingston sells specific 16MB flash cards for the

The website for the consultants program/cisco press
seems to be down, instead of just under-reconstruction. Does anyone have
the toll-free number to order books?
Does anyone want to form an ISP-Dial online study
group??? I'm getting a few of the course manuals, but I'm looking for
other post-CCNP level hopefuls that are a few months away from taking the
lab...
I just purchased an 804 on Ebay, now I'm selling it
