RE: Extended Vlan across Wan [7:54866]
I'm surprised Howard hasn't chimed in yet, this is definitely a what problem are you trying to solve sort of case... More details please. Personally, I don't believe VLANs should extend outside a building (even with Dark Fibre); but perhaps you have requirements that would justify this... -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of gladston vidali Sent: Friday, October 04, 2002 9:05 AM To: [EMAIL PROTECTED] Subject: Extended Vlan across Wan [7:54866] Hi Guys, Could you give me your opinion about the following ?

Couldn't you bridge the VLAN's into an ATM 1483 bridged PVC, point to point across the WAN at both ends? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of gladston vidali Sent: Friday, October 04, 2002 4:05 AM To: [EMAIL PROTECTED] Subject: Extended Vlan across Wan [7:54866] Hi Guys, Could you give me your opinion about the following ?

Re: Extended Vlan across Wan [7:54866]
This thread brings to mind a question I've had for a while. It appears sometimes that a lot of people think ATM is difficult to understand, implement, support. Why is it that? My ( albeit limited ) exposure to ATM from the customer side is that ATM is basically every bit as easy to set up and run on your typical WAN as frame relay. Yes there are some additional bells and whistles which can become complex as you do more complex things. And obviously, complex corporate networks might make use of a lot more ATM specific features. But in general, you set up the PVC's, configure the IP address ( or enable bridging ) and do everything else pretty much the same was as you do with frame relay. Any thoughts?

Re: Extended Vlan across Wan [7:54866]
Part of the complicated image probably harkens back to early ATM campus applications, pre 100BaseT. As you mention the configuration of ATM is very similiar to frame though you need to shape your ATM traffic assuming a non UBR PVC or your goodput will be unacceptable. For whatever reason Cisco does not take into account the ATM overhead when calculating your shaping parameters, i.e. if your shaping a 5M pipe subtract %10, police at 4.5M for aal5snap. Now LANE I think is primarily where ATM configuration/ especially troubleshooting fear comes from, just say no to LANE! If you simplt want to extend a few VLANs over your ATM and you have LANE cards and an RSM/MSFC you can bind the PVCs to the VLAN to extend a VLAN/s across ATM.

RE: Extended Vlan across Wan [7:54866]
Chuck, I agree with you. I worked for FORE Systems doing nothing but ATM to the desktop for 4 years before moving to a company with all cisco. Not much harder to understand, as long as you understand basic networking fundamentals and the fact that these are just 2 different technologies that have their place in the network.

Re: Extended Vlan across Wan [7:54866]
I think some people tend to be intimidated by ATM more than by frame relay because it is more expensive to get into a home lab and most of us are less likely to have a job configuring ATM on a regular basis than configuring frame relay on a regular basis. Yes, I know you can get ATM in your lab with 7000s and a non-Cisco switch at an almost-reasonable price, but it's still a bit much too much money, bulk and noise and power consumption.

CL: that's one of the downsides of my job. I'm selling a lot more ATM related things, and generally I am responsible for writing the configurations. I have no way of mocking up customer ATM networks in my own lab, so I have to rely on the basics of frame relay. well, now I know enough QoS stuff to be dangerous. ;- Tom Larus, CCIE #10,014 Daren Presbitero wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
