Did you mean virtual routers? I've never heard of logical routers although I've configured juniper netscreens numerous times. Virtual routers are in-built into Juniper Netscreen's router software architecture and are extremely easy to configure. I don't think extra software or hardware is needed. What do you mean by 'PIC'? ________________________________ From: ibtisam jamal <ibty.jamal@gmail.com> To: Skunkworks forum <skunkworks@lists.my.co.ke> Sent: Friday, May 8, 2009 10:12:46 AM Subject: [Skunkworks] juniper logical routers Hi all, Has anyone configured logical routers on a physical router specifically for juniper. i have read that the requirements for a separate routing engine and separate interfaces on PIC.
