Re: Hub to Hub through 2600 [7:16328]
You can't do full on a hub. Put your routers back to half and it will probably work. If not, make sure your workstations didn't auto-screwup and go full as well.

Re: ip default-network [7:16507]
It's not dynamic. I can't ship that router out with the same config to anyplace in the world. Using a default network, you can. It will come up, peer, get it's routing table, and send it's default stuff towards home. Let's say for instance that you have a large core network. You want all traffic that isn't in the routing table to not go to Null0, but you want it to flow down to this core and let the core deal with it. You may want this for a number of reasons, most obviously if you default route to the Internet, but also if you are running multiple routing protocols and not redistributing between all of them. You can then set a loopback on all the core routers on say '192.168.200.0' network. Then on all your routers you deply, you set the ip default-network to 192.168.200.0. Now no matter where you drop that router, if it's got a routing table, and that table knows at least one person that can get to 192.168.200.0, then you're set. No more configuration. Let's also say that edge router has an isdn dial backup. If your primary goes down, and the other comes up, when the new routes flow in, it will take the new interface with the new next hop to the core automatically - no route changes. The new routes will just get tagged as default candidates and away it goes. -me Rick Foster wrote: How is this different from configuring two different default routes for the same network e.g. ip route 10.0.0.0 255.0.0.0 202.33.22.11 ip route 10.0.0.0 255.0.0.0 203.44.33.22 ip route 10.0.0.0 255.0.0.0 204.55.44.33 Regards ...

Re: voice lab [7:16561]
Depends on what type of Voice over IP you want to do. If you just want to do an h323 gateway, you will need to have at least a 2600 with a VIC module and various cards to go in it. FXO will go towards the CO on a regular dialin line. You can then write some rules to allow something like netmeeting to dial out on that phone line. If you want to simulate a phone switch, you'll need an FXS. You can then plug a regular phone into the FXS port, the telco into the FXO and setup some call routing. Again, you could setup H323 to allow netmeeting to call that phone, or for that phone to call netmeeting. If you've got a real PBX to work with, you'll need either a EM card or a voice PRI card. EM will give you dial ports that you can configure, however, you won't be able to pass the call information across that you can with a PRI. -me george gittins wrote: any pointers has for what type of hardware would i need to make voice over ip lab?

Re: ip default-network [7:16535]
You can't answer the question with the information you gave. You just say that there are three upstream providers with OSPF and BGP. You don't say which routes come over which and what their weights are. Just check your routing table. Whatever path has the best routes to one of the networks you specified will become the gateway of last resort. As for their precidence, I don't know. As with most things cisco, it could either be the order that they are in the config script, top down, or the order of their sorted queue. So it may go through all of the best 10 routes before the best 192 routes. That's something to put into lab. Usually, you only have one default network. The only case I can think of that you might have more is if you want everything to flow to data center A if there isn't a route unless data center A gets hit by a large falling rock, then transfer all the default traffic to data center B. To have more than one increases complexity, and with complexity comes failure. Mike Vijendra Jaiswal wrote: My query is still unanswered !!

Re: Why Should the Binary Math Method Be Used to Subnet [7:15354]
The binary method is nice because it is what the router does. In addition, in the process, you get out a lot more information. For instance, you can quickly determine the class without having to memorize all of the ranges with the following binary patterns: Class A: 0 [0-127] Class B: 10[128-191] Class C: 110 [192-223] Class D: 1110 [224-239] Class E: [240-255] Not to mention, as you run the bits you can see exactly what is happening. Granted, there are still tricks. For instance, the following table helps calculate things quickly: 128 64 32 16 8 4 2 1 128 192 224 240 248 252 254 255 Notice that it's just the bit values across the top, and the sum of the bit values across the bottom. So if you write that out, you can find out exactly what your masks are and the bit patterns that go with them without any tricks. Mike Priscilla Oppenheimer wrote: Well, I have to admit to never really understanding the shortcuts that I have seen people use. ;-) I guess I'm brain damaged, but I have to do it in binary. As far as tools are concerned, I totally agree with the person who pointed out that in design meetings, you often don't have any tool handy except your head.

Re: Fw: DE bits [7:15210]
Yes, DE bits will stay on as it traverses the frame network. With DE set, any switch along the path that has congestion will toss you out before one without DE set. If you are running a CIR of 0 (as with most Sprint frame circuits), you always run the risk of having to retransmit. However, they supposedly design their frame network so that you never have to.

More times than not the frame cloud will mark your frames DE even if you not exceed you SLA. Then it's time to call the provider. Generally, DE bits have nothing to do with port speed. Port speed is just the speed of the link you have to the frame switch. Traffic shaping has more effect on the rate you send to each PVC. It's a little complicated.

Re: TCP/IP [7:15213]
Not quite true. TCP/IP CAN be done in silicon. However, it's not a good idea to do this. The reason being is that if you have a bug in your stack, you gotta toss the whole card.

Re: IP address space allocation management [7:15130]
How big is your enterprise? Lucent QIP is what I see most in large enterprises. It has it's issues, but it's all around a very good product. If you do go with something like QIP, it will provide DHCP, Dynamic DNS, inventory (if you get that far into it), and a lot more.

Re: urgent problem [7:14942]
Yeah - I've had a similar problem with a 3640 running 11.x code. Up it to 12.0.18 if you can and it should go away. Mine has been rock solid ever since. Other things I noticed, besides the intermitant connectivity, would be that the whole box would hang while you were on it for periods of time. Then it come back like nothing ever happened. All related to memory allocation.

Re: urgent problem [7:14942]
Generaly, memory leaks are not hardware related. They're code related. Either way, the only real way of isolating them is process of elimination. Which means, turn down extra services, update OS, etc. Since I doubt you can turn down any extra services without impacting your users, upgrading to see if it goes away is the next simplest without impacting everyone (other than for the reload of course). You could also just search CCO or call TAC and see if there is a known issue with that revision of code as well.
