Hello, A bit off-topic and maybe stupid question: I was told yesterday, that a Hungarian telco/ISP is experimenting with EDFAs. My friend said that the box looks like if they just brought it from a research lab (however it's a commercial product). How common is it nowadays to use EDFAs in ISP backbones? Please reply me off-list. Thanks. Andras

Is it not possible to do: Make a zone file Put views in it just for that zone Make another zone file for a different domain Put view in it that overlap the first zoenfiles, but won't conflict because they are in a different zone. By overlap I mean something like this: Zone1: 'internal' = 10.0.1.0/24 + 'external' = 192.168.1.0/24 Zone2: 'internal' = 10.0.0.0/16 + 'external' = 192.168.0.0/16 Zone3: 'internal' = 127.0.0.0/8 + 'external' = 10.0.0.0/16 Make sense?

Cisco very recently published "IS-IS Network Design Solutions", ISBN 1-57870-220-8. I don't know of any other good references. It's obviously Cisco-centric but does try to cover questions like "why do I want IS-IS instead of [mumble] as my IGP". > -----Original Message----- > From: Greg Pendergrass [mailto:greg@band-x.com] > Sent: Thursday, April 25, 2002 4:00 PM > To: 'Nanog@Merit.
