Thanks for explaining that. I can't remember seeing 'logical routers' in the netscreens I handled. Below links might help: http://forums.juniper.net/jnet/board/message?message.uid=18701 http://www.juniper.net/techpubs/software/junos/junos73/swconfig73-routing/ht... Never personally done it before, though. Good luck Bernard ________________________________ From: ibtisam jamal <ibty.jamal@gmail.com> To: Skunkworks forum <skunkworks@lists.my.co.ke> Sent: Monday, May 11, 2009 5:16:38 AM Subject: Re: [Skunkworks] juniper logical routers virtual router can have a single routing table i.e VRF virtual route forwarding.but a logical router will act as a router will carry many virtual routers and many routing tables..I think netscreens are firewalls.PIC is a physical interface card . The essence is the logical router will behave like a router not a subset of the router. On Fri, May 8, 2009 at 8:46 PM, Bernard Owuor <b_owuor@yahoo.com> wrote: 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. I need advice from someone whose done this ...need to know the pros n cons. regards, _______________________________________________ Skunkworks mailing list Skunkworks@lists.my.co.ke http://lists.my.co.ke/cgi-bin/mailman/listinfo/skunkworks Other services @ http://my.co.ke Other lists ------------- Skunkworks announce: http://lists.my.co.ke/cgi-bin/mailman/listinfo/skunkworks-announce Science - http://lists.my.co.ke/cgi-bin/mailman/listinfo/science kazi - http://lists.my.co.ke/cgi-bin/mailman/admin/kazi/general
