Hi Doug, Thanks for the reply. You are correct, each logical system gets its own rpd process.
I managed to get access to an M7i and indeed you can do 15 LS's on them. Each rpd process only takes a couple of MB RAM, and seem to be quite light on CPU (barely even registers) so it looks promising for an RE-400 with only a couple of hundred MB of RAM even. Still need to test with a few more features, so this might impact on RAM and CPU. We'll see over the next couple of days as I play around some more. Hopefully this information is helpful for someone else. :-) Tom On 1 March 2012 05:37, Doug Hanks <dha...@juniper.net> wrote: > 15. Should be fine for personal use.
