bgp best practice question
I need to make one of our data centers internet accessible, i plan to advertise a /24 out of our existing /22 network block at our new site. My question is for our main datacenter, is it a better idea to continue to advertise the full /22 or advertise the remaining /23 and /24 networks ? - Jon Heise

LX sfp minimum range
we are moving a router between 2 data centers and we only have LX sfp's for connection, is there any issue using LX sfp's in a short range deployment ?
juniper mx80 vs cisco asr 1000
Does anyone have any experience with these two routers, we're looking to buy one of them but i have little experience dealing with cisco routers and zero experience with juniper.
automated config backups for SFTOS
Does anyone know of a method of automating config backups for force10 switches running SFTOS ? I've got an python expect script that works on our routers running FTOS, it uses a role account that can show the running configs without having to use the enable password. i could expand the script to use the enable password but i'm hesitant to have it lying around in a script Jon Heise
