Re: [c-nsp] prefixes in AS-Set

[Rob Lister]

Yes... I would probably not bother to filter every peer, but just set max 
prefix (if they are an IXP peer for example) or otherwise you could end up with 
a lot of prefix lists and I think the router can only hold so many prefix list 
entries.

Not every peer is going to have info in the db and/or it may not be up to date 
etc.

This approach would be suitable for where you have downstream customers and you 
want to filter what they can announce to you, and you want a way to automate 
the updating of prefix lists accepted from customers (Many transit providers do 
it this way)

Regards,


Rob

+1 for Opengear. Good functionality, especially since they now make
a Cisco Pinout version, so you can just use the existing Cisco DB9
adaptors rather than having to make/buy special cable / DB9 adapter
for the Opengear.

Has some very nice features such as two users being able to login to
the same console session at the same time and share it.

Also it has good logging of output from console to syslog / log file
etc, so if the device crashes completely or fails to boot etc then you
have a nice log file of what was received on the console when it died!
