I was wondering what's the common practice among ISPs regarding the  
"neighbor maximum-prefix" option in Cisco and Juniper routers?
By default this option is disabled in both Cisco and Juniper boxes,  
but was wondering if anyone in this list already configured it?



I use it facing full-route upstreams (250k at present) and IXs (~50% more than I expect there) where I want to receive 
all routes announced without having to change route filters every time there's a change and, so, don't want a route 
filter. It's not necessary on customer facing interfaces as you use a route filter and only allow what's agreed on.
