Re: Priscilla Oppenheimer [7:49347]
Peter , The book says clearly that the interface is pingable. Even more, I have tried it and it really works. I just took two routers connected by back_to_back serial cables with IP unnumbered configured on both. When I unplugg the Lan interface of one them, this router is still reachable by the IP address.

Caller ID for Callback [7:49377]
Anybody has experience in setting up Caller ID for Cisco routers, to control Callback features for remote users? Is this features supported on Cisco routers? I have experienced setting up using Lucent products, and now asking for any advice regarding this. Cisco routers support the remote access dial-in for remote users throught its analog modem module, but it is not yet supported on the software. Can Cisco2600 or Cisco3600 able to do that, or I need AS5300 to achieve this?

Re: Priscilla Oppenheimer [7:49347]
Richard, not that I doubt you ( because I have never tried this myself ) but would you mind posting the relevant configs and the results of the ping to the list so we all can see? simple cut and paste is fine. Knowing that it works, lets see if intellectually speaking we can come up with a good explanation. 1) RFC 1812 talks about unnumbered interfaces. Without looking it up, IIRC, the unnumbered link lives and dies by using a router i.d ( RID ) to identify the end points. 2) a ways back, ( and I forget the context ) there was a discussion about multiple interfaces having the exact same ip address and how was this possible. The answer seemed to be ip unnumbered. again, IIRC, someone was able to provide a show ip int brief or some other output that indeed did show several interfaces with identical ip addresses. Dan Cotts - for some reason I recall you being part of that discussion. do you remember? 3) those things having been said, then one rational conclusion is that ip unnumbered associates a particular ip with the unnumbered link, and that a monitoring tool could indeed ping the interface. I might want to know a bit more about the order of things. IIRC ( and this is taking a bit on faith ) an interface in shutdown mode doesn't register as an ip endpoint. maybe if the unnumbered is configured while the interface is up, and then later if it is shutdown, the unnumbered config remains in place?

Re: CCIE Home Lab [7:49369]
DO NOT buy a Cat 5500 for the home lab if you are doing so for the CCIE. They are taking the 5500 off the Lab. Read the list about these and other recent changes. They were announced less than a month ago, and there has been a lot of discussion here. Now you could still buy a Cat 5500; just don't do it because you think it will be on the CCIE lab. They are dropping in value daily, so you might be able to learn something for CCNP switching test on a very cheap Cat 5000. My Cat that I was proud to have put together at reasonable price will go someday for MUCH less than I paid for it. Also, do not even think of buying a 3900 TR switch.

VoIP Bandwidth Calculation you wil have to consider two VoIP [7:49381]
Hi All, Using the standard formulas, I see for a bandwidth required for a g.729 call is 24kbps without RTP compression.I used to do the same when using other codecs. Recently I came across some VoIP documentation which said that you will have to consider two RTP flows to simulate a call, and hence the requirement for Bandwidth doubles.say g729 24 kbps becomes almost 48kbps if u consider two RTP flows. Any help will be highly appreciated.

That is good. I wasn't saying necessarily that it wasn't, I was just saying that the ISP essentials quote you gave didn't say that it wasn't specifically. Again though, can you quote msgs to make the trail easier for those of us who don't a) read the newsgroup, and b) arrange by threads. tks pete At 02:07 PM 7/22/2002 +, richard dumoulin wrote: Peter , The book says clearly that the interface is pingable.

RE: Connectivity between Two Offices [7:49236]
Kevin, I know it's not really what you're asking, but I have a suggestion...If your buildings are right across the street from each other as you say, you would be MUCH better suited to invest in a line-of-sight wireless solution between buildings that will net you 11+ MB/sec. Short distances like that always seem to have higher bandwidth requirements, and from an ROI standpoint, a wireless solution with no recurring fees will pay for itself much faster than a little T-1 that you have to pay for every month. If you are bound to using a T-1 by some political or administrative requirement, given that you have spelled out what equipment you have, then I'd just recommend that you by the T-1 WIC cards and associated NM's for the 2600's and that'll do it. Use straight HDLC, as it produces the least overhead. Hope this helps. Kelly Cobean, CCNP, CCSA, ACSA, MCSE, MCP+I Network Engineer ATT Government Solutions, Inc.

DHCP Server on Multiple VLANs [7:49403]
Hey guys, I have a Cisco 3620 connected to a 2948G-L3 which in turn provides layer three services to a cluster of 3548XLs. I have 9 operating VLANs and have been trying to work out a scenario for DHCP in my environment. Right now, we assign static IPs in all 9 vlans because we do not want to provide seperate DHCP servers for each. If we could find a way to get one server to provide DHCP to all the VLANs then we could implement it. The trick is, each VLAN is a different subnet. I had heard that if you use the 3620 as a DHCP server, create subinterfaces on a FE port using ISL and assign IP addresses appropriately, and create multiple DHCP pools, then the router would issues IPs from pools that matched the interface it drew the request from. However, when I try this it just issues IPs from the first pool until it is full and then moves to the next. Is there a way to make sure the router assigns correct IPs on the correct sub-interfaces? Is there a 3rd party DHCP server that would do this better? Let me do a sample config to show what I tried. Each network has a network printer at .200 (don't ask) and a router sub-interface at .1 except the 10.10.10.0 network which has reserved IPs through 100, but still a router interface at .1 Here's the Cisco 3620 DHCP portion of the config: ! ip dhcp excluded-address 10.10.10.1 10.10.10.100 ip dhcp excluded-address 192.168.1.1 ip dhcp excluded-address 192.168.1.200 ip dhcp excluded-address 192.168.2.1 ip dhcp excluded-address 192.168.2.200 ip dhcp excluded-address 192.168.3.1 ip dhcp excluded-address 192.168.3.200 ip dhcp excluded-address 192.168.4.1 ip dhcp excluded-address 192.168.4.200 ip dhcp excluded-address 192.168.5.1 ip dhcp excluded-address 192.168.5.200 ip dhcp excluded-address 192.168.6.1 ip dhcp excluded-address 192.168.6.200 ip dhcp excluded-address 192.168.7.1 ip dhcp excluded-address 192.168.7.200 ip dhcp excluded-address 192.168.8.1 ip dhcp excluded-address 192.168.8.200 ! ip dhcp pool Vlan1 network 10.10.10.0 /24 dns-server 4.2.2.1 default-router 10.10.10.1 ! ip dhcp pool Vlan10 network 192.168.1.0 /24 dns-server 4.2.2.1 default-router 192.168.1.1 ! ip dhcp pool Vlan20 network 192.168.2.0 /24 dns-server 4.2.2.1 default-router 192.168.2.1 ! ip dhcp pool Vlan30 network 192.168.3.0 /24 dns-server 4.2.2.1 default-router 192.168.3.1 ! ip dhcp pool Vlan40 network 192.168.4.0 /24 dns-server 4.2.2.1 default-router 192.168.4.1 ! ip dhcp pool Vlan50 network 192.168.5.0 /24 dns-server 4.2.2.1 default-router 192.168.5.1 ! ip dhcp pool Vlan60 network 192.168.6.0 /24 dns-server 4.2.2.1 default-router 192.168.6.1 ! ip dhcp pool Vlan70 network 192.168.7.0 /24 dns-server 4.2.2.1 default-router 192.168.7.1 ! ip dhcp pool Vlan80 network 192.168.8.0 /24 dns-server 4.2.2.1 default-router 192.168.8.1 ! interface FastEthernet1/0 description connected to Private Network no ip address duplex auto speed auto ! interface FastEthernet1/0.1 encapsulation isl 1 ip address 10.10.10.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.10 encapsulation isl 10 ip address 192.168.1.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.20 encapsulation isl 20 ip address 192.168.2.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.30 encapsulation isl 30 ip address 192.168.3.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.40 encapsulation isl 40 ip address 192.168.4.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.50 encapsulation isl 50 ip address 192.168.5.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.60 encapsulation isl 60 ip address 192.168.6.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.70 encapsulation isl 70 ip address 192.168.7.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.80 encapsulation isl 80 ip address 192.168.8.1 255.255.255.0 no ip redirects !

Re: VoIP Bandwidth Calculation you wil have to consider two [7:49404]
Steve, It makes sense to consider two RTP flows as a conversation consists of full-duplex transmission. both people speak at the same time in a normal conversation, so that is why. please let me know if you have any thoughts on this neil Steven A.
