If it is used for backup there will be a routing statment that uses the isdn pri ip address as the gateway. it will have a higher number in the metric that the frame relay route.

You can also request the dlci numbers used in your frame relay network. It can help keep the information logical with multi node networks. with just two sites it would not matter and the telco will probabley map dlci 16 to dlci 16 in that situation. If you can get B8ZS and ESF. Mainly so that...

If the interface you are talking about is the wic 56k, then the router does recognize it! But it looks like the bootstrap software 11.7(ax) does not suport the wic 56k. If you do a show int on the router does it show the wic 56k interface? and can you configure the interface?

Do you have a copy of the IOS on your network? Or do you have a support contract with Cisco? If so you can go to CCO and download it from the software center. Failing ether of these you might have to buy an IOS from a retailer. Good luck

Yes they would be different broadcast domains. And unless there is no other way to make the connections you want, it should be. How many PCs do you have at each location? You can set the cisco routers to forward broadcasts but that is turned off by default. For the routers to route they have to...

Hi Scully, To block traffic or ports coming in from the Internet, apply your extended access list on the T1 interface s0/0 and apply it in. Look at it from the routers perspective. If you want to filter incomeing traffic then use in for incoming. The ACL is applyed at the interface level. The...

rcasta, Well first to send data across the ISP you will need to use ip routing. And you will be limmited to the bandwidth provided by your ISP. If your ISP is providing you with 60mbps of internet bandwidth then you have more than a ds3, or T3 at each site. but anyway, I would sugest that you...

How are the users connecting to the router? Are you disabling the user at the PC? Etherway disconnecting the infected PC should free up the memory sued to pass the traffic load. Unless its your logging the is useing up all your memory. Could you be more specific on your problem.

Yes on the Gateway!! But the computers on the network allready have a gateway. Why? is ether or both the networks connected to the Internet? Or is their gateway an file server? So to test you could hook 1 computer directly to the router with a cross over cable. set the address and gateway, then...

EIGRP will generate hello messages. The timer for these messages is configuable. When the wireless link drops the routers will recompute the route to the destination. and send packets accordingly. \

Yes a Hacker could have deleted the files. You said you looked at the files in flash? If flash is empty you will have to have an IOS to load. Check on your network for an IOS image. It will start with c2620 or c2600 probably the latter. You can buy an image from CDW or other retailer. Its a...

There are several ways to set up an extended lan. If you are using a router capable of tunneling or vpns you can connect that way. Serveral quiestions to answer are but not exclusive to. What protocals do you need between the lans? Are your computers IBM, Apple, or? Do you use wins or name...

Thanks I will take a look at it

I'm not real clear on you topology. if one or all links go a the frame relay cloud then the bouncing links are probably associated with the lmi. check with the service provider(telco) and see what lmi types they suport. the lmi will advertize the dlci to you but you will have to configure it...

just powering up the router is not enough. you will have to access it via the console port and configure the ethernet port first. hopefully you have the db9 adapter and the rollover cable to go with the router. If not you can get the pinout on ciscos web site. just add an ip or ipx address to...

on the fr interface you will need to ietf encapsulation unless both of the other routers are cisco. then you can use the defalt fr encapsulation of cisco. lmi can be ansi or cisco depending on you telco requirments. you can use an access list to block all wan requists except to the ip...

first question c is correct. second question if i read it right a and b are correct, you add the ip address to the subinterface and that associates it with the dlci. Yes you can corectly configure an unconnected frame-relay interface but untill you have a frame-relay connection there will be no...

actualy no I dont but seeings as you are trying to communicte via isdn there should be no capatiblity isues. just configure the cisco to use the isdn line as a backup and if you using ip to route set the correct address on the int.

you could go ahead and set up a network just for the wan link. then if you nat at both locations they could use the same network addresses but would see each other as a different network.

sounds like you have a bad patch cable, or a port on one router or the other. Ethernet devices should listen for traffic befor sending a packet! one of your devices is not listening to the traffic before sending. as there is no way the two routers will try to send at the same instance that many...
