Re: PRI woes...switch vs. switch
No nfas here...just plain 'ole PRI signaling. We busy out a PRI, then dial and watch calls hit the next PRI for testing purposes. Actually, we ended up finding out that 5ess switches running national/standard software by default do not offer the "maintenance" state for b-channels( only "in-service" and "out-of-service"). --- Eric Lofvenborg <[EMAIL PROTECTED]> wrote: > Hi all.

RE: cd burner LAST
OK, here is the last waste of time/bits/bandwidth,etc on this... Sure a positive attitude is great, and being helpful is great. And I don't mind hitting delete several hundred times each day BUT OFF TOPIC questions should go somewhere else. --Bottom line--. I mean the ? about the CD burner is nowhere near the target. Questions about blocking Napster or how to resolve problems with Microsoft domain controllers are borderline. Actually, the questions about PDCs and BDCs bother me more than other borderline errors. I'm sure that MS has ample information about this somewhere else. In fact, I bet they even have their own study groupbut maybe the people at the MS groupstudy aren't as sharp as those at Cisco/groupstudy... :> --- hao vu <[EMAIL PROTECTED]> wrote: > ...

Hi All, Any telco guys know what a "BIPP" (BIP)? refers to? One of our guys here says it's a circuit "out to the Internet".

Question for isdn/telco gods...
Another question for current (or former) telco switch techs... We are having issues again trying to issue the "isdn service ... dsl 0 state 1" command to put all the b-channels in a single PRI into 'maintenance' state. Telco claims that we are sending 'ni-2' protocol service commands. We don't even have the option of running 'ni-2' as the switch protocol. Is it really possible telco is seeing ni-2 statements coming from our NAS when we don't even have that protocol option? Our main options for the NAS (in the US) are national, 5ess-custom or dms-100. Is telco misinterpreting something we are sending? OR Is our NAS sending ambiguous information to the telco LT switch?? Thanks! NAS = AS5800, running 12.0.5(?) s/thing like that... = Don't forget to cross your digits... Dan West -- CCNA, CCNP (in progress) __ Do You Yahoo!? Get personalized email addresses from Yahoo!

Re: ip route question
Yea, arp lookups will be performed until the specified interface of the default route is found. This is called recursive arp (??) I think this is related to the idea of setting an addresss way upstream as the default route for your AS. In other words, efforts should be made to set the default route as something closer to a more aggregated network. I know I am not making any sense because it's too early in the morn. Oh well, I know s/body will slap me down if I make a mistake. That's what makes this group so cool, IMHO. --- "Stull, Cory" <[EMAIL PROTECTED]> wrote: > > I remember reading somewhere that when you add an IP > route the ip address of > the next hop doesn't necessarily need to be the next > hop or even on the same > subnet..? > > Reason for asking > > > I want RouterC to have to go to RouterA before going > out routerB to the > internet because routerA and routerB are on same > ethernet segment with a > websense internet filter on that segment being used > to filter internet > traffic.Right now RouterC traffic goes > straight to routerB to > internet and doesn't get filtered through the > websense filter. > > Comments? > > Thanks in advance as always. > Cory > > > > (central site) > RouterA \ >\ > \ > \ > > RouterB\ > RouterC(remote > site) > (central site) \ > \ > \ > \ > Internet > > > _____ > FAQ, list archives, and subscription info: > http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] = Dan West -- CCNA, CCNP (in progress) __ Do You Yahoo!?

Re: Using Register IP Address on your Private network
SmartAlec answer: Because people don't have the technical knowledge to implement NAT. I would bet that many folks out there even in the networking world have ever heard of it. Otherwise, like others have pointed out, people may encounter problems when gaming online, running VPNs, etc. --- [EMAIL PROTECTED] wrote: > > With the shortage of registerd addresses out there > and 99 percent of all > programs work with NAT.

Re: AS numbers - Is there a global crisis?
I wouldn't think that's t much of an issue. As far as I understand it, you only get assigned a public AS number if you're a m_a_j_o_r provider--like PSInet, AT&T, MCI, etc... If you're a mid-sized to smaller organization, you probably can get by using a private AS from a larger provider.

CSMA/CD : full duplex
Sorry to ask such a simple question--but the CCNA book is still unclear as to what's going on. Half-duplex ethernet uses CSMA/CD for arbitration on the link. Does full duplex use it as well for arbitration? The book makes it sound like if you are running full-duplex that the CSMA/CD is not necessary. It mentions half-duplex looping a duplicate frame onto the recieve wire from the transmit wire. Thanks. __ Do You Yahoo!? Send instant messages & get email alerts with Yahoo!

frame relay newbie question
Is it common/practical to run IP and IPX over the same frame relay subinterface? I am only asking because in Lammle's CCNA prep book it is mentioned that one of the advantages of subinterfaces is that you can run IP on one and IPX on another. BUT, the example directly following that statement shows IP and IPX running on the same subinterfaces. More importantly, is IPX even going to be an issue much longer? Thanks. __ Do You Yahoo!?

BGP question
My former employer (an ISP) had BGP peering with our upstream provider(Telco). As I understand it so far, BGP4 is used to advertise routes between autonomous systems. One day I ran a web-based traceroute to my old haunt and it showed them having the same autonomous system number as our bandwidth provider. Were we unnecessarily using BGP? I don't understand why our telco and we (the ISP) had the same AS number. Am I misunderstanding the purpose of the AS number in BGP? Many thanks. __ Do You Yahoo!? Yahoo!

Syntax confusion
Can anyone tell me why Cisco made the bit syntax different between access lists and the "ip route" command??? Example: permit ip any host 10.1.1.0 0.0.0.255 In this case, the zeros in the second column match exactly and the 255 is a wildcard. BUT then: ip route 10.1.1.0 255.255.255.0 w.x.y.z Here, the 255 matches exactly and the zero looks like wildcard. Is it just me or is this unnecessarily absurd?

Cisco Press Errors
Does anyone know of websites/newsgroups that post corrections to mistakes in Cisco Press publications? They may be official or not-- I don't care. I found a subnet address error in the Routing TCP/IP book for one of the static routing config examples. I was pulling my hair out thinking I was not calculating the subnet address correctly. That was an error I could iron out myself but I am concerned about more broad concepts and such that may be misprints... Thanks. ===== Dan West -- CCNA __ Do You Yahoo!?
