RE: AW: ISDN problems... [7:34324]
Router(config)#access-list access-list-number [permit | deny] {protocol |
protocol-keyword}{source source-wildcard | any}{destination
destination-wildcard | any}[protocol-specific-options] [log]
The more complex form of the command references an access list, allowing
finer control of the definition of interesting traffic than the dialer-list
command

RE: general question on rip/igrp/eigrp over isdn [7:43419]
You have to implement something called "snapshot routing". This is when you can configure your ISDN line to make a connection to a remote site say...once a week or so...and obtain routing information via the said routing protocol.

RE: Off Topic - inauspicious beginning [7:45592]
Sounds like it was a physical layer issue: bad rollover or, bad db9, or bad serial port on the computer Swapping out each of the above, one at a time, undoubtedly led to your solutionI think. The other possibility was that your keyboard was messed up and sending the wrong keystoke combos.

RE: Voip/Internet Telephony [7:45915]
VoIP is any time you take sound and packetize it using standard (H.323, SIP, etc) or non-standard (Cisco's Skinny) protocols, which, in turn, allows one's voice to travel over IP. When you use VoIP to inmitate and/or expand upon traditional POTS telephony (ip-to-pstn, call forwarding, call-waiting, the stuff that Howard says above), it is more-encompassing to use to use the term IP Telephony. Internet Telephony -- well, the word Internet implies that data is traversing different ISP backbones (autonomous systems) between the two or more VoIP callers. I would say Internet Telephony is one way to do IP Telephony but that IP Telephony doesn't need to use the Internet such as when it is used on a LAN only or when the WAN does not traverse the Internet.

RE: ip nat overloading question [7:46037]
Overloading, or PAT, works only when traffic is initiated on the LAN and terminating on the WAN. Then, as you say, a nat translation is created so packets can go back and forth between the two. WAN traffic can then only hit the LAN for the duration that the translation remains in the nat table. If you want to have traffic initated on the WAN to reach your LAN, you need static NAT in the form of: ip nat inside source static [local-ip] [global ip]. This creates a one-to-one mapping between your local ip and the global ip, not one-to-many as in PAT. The only other nat option is to use TCP Load Distribution which likely doesn't apply to your circumstance.

RE: Multicasting software [7:47056]
The PERL multicasting module works great. I use that to test multicasting in my router lab. I think it only works in linux. Search for it at: http://search.cpan.org -- you'll need to know a little bit about PERL though. But the examples given will give you the code you need.

RE: OSPF point-to-multipoint 32 mask [7:56136]
/32 mask always shows up under the "show interface" commands despite the actual netmask. I'm not sure what you're asking in the other question.

Cisco Netacad for 640-603 [7:52358]
Hello, Was wondering if anyone has taken the Cisco Network Academy semester-long course (sem. 5) for 640-603 (Routing)? If so, did you find it alone was a good prep for the exam?

Anyone know of a cisco users group in the boston area? Secondly, what goes on at these gatherings?

RE: Boston Cisco Users Group? [7:52359]
If anyone is interested in starting a Boston-area cisco users group...let me know. Just pop me an email at [EMAIL PROTECTED] with: 1. name 2. address 3. telephone number 4. Certifications you have 5. Certifications you plan on pursuing over the next 6 months 6. Optional: Any ideas about what this group could do together 7. What cisco products you work with or have worked with 8. Current or Last Job Title [Don't worry, I'll keep this stuff confidential]. I have consulted with a training center/cisco network academy that has space I know we could use in Davis Square adjacent to the T-stop -- just one idea about space we could use. (It also has 2500 routers and 1900 switches).

RE: ADSL Link [7:52978]
Rarely is DSL used in a dedicated point-to-point manner...though it is possible on a large campus between buildings. Most ADSL connections are akin to a T1 line between you and your provider since you have, more or less, a dedicated copper run between your house/business and your service provider's DSLAM. Once it hits the edge of your service provider cloud, the copper goes into the DSLAM and out a high-speed connection (OC3, DS3, etc) to an access concentrator. From the access concentrator, it traverses the service provider's backbone this is why ADSL is more accurately described as a packet-switched connection. Since ATM is at layer 2 think of ATM connections (an example of a packet switched connection) except remember that now the ATM can traverse your copper phone lines. Finally, the traffic will hit other autonomous systems (the Internet) from your provider's backbone.

Re: SIP vs H323 [7:53852]
Ok, so SIP is nowhere near useless. It is being used all over the place and will eventually replace H.323. Telcos like Vonage (which uses Cisco SIP equipment), deltathree, and Denwa are using it for last mile telephony connectivity for residences and enterprises, and WorldCom, after surfacing from its financial issues, will be using it on its global network as well. Microsoft has built a SIP client into Windows XP (Microsoft Messenger) and SIP is very flexible and extensible and the best place to start is http://www.sipcenter.com. PBX manufacturers like Mitel and Siemens have developed their PBX completely around SIP. To get back to Cisco (as this is a Cisco newsgroup), Cisco has taken the time and $$ to start to develop SIP functionality in its products despite the fact that it isn't need for AVVID at all. Though their initial SIP focus is on carrier-class products (since that is the logical choice -- see my list of companies above), my bet is that SIP will surface as a more central part of the AVVID architecture for the enterprise. A good Cisco link is here: http://www.cisco.com/warp/public/cc/techno/tyvdve/sip/prodlit/index.shtml or here (which displays more enterprise scenarios): http://cisco.com/univercd/cc/td/doc/product/voice/sipsols/biggulp/index.htm Regards, Jason Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=53856&t=53852 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
