Setting up communication between an Olive and GNS3/Dynamips router

Very useful, allowing a dynamips/gns3 ios router to talk to a Junos Olive.

Creating a J-series Junos or J-series Junos with Enhanced Services Olive – the easy way

Here is a way to create a J-series/J-series Enhanced Services Olive. This is a more straightforward way of creating an olive.

Flavors of Olives

When someone refers to an Olive they are referring to Junos running on top of a Freebsd install, whether it be a pc or a pc running some virtualization software like Vmware or qemu. An Olive has tradionally been based on  M&T series software which have some of their capabilities offloaded to another piece of hardware, such as an Adaptive Services PIC or Multiservices PIC or ASICs processors. There are other lower-end routers where all processing is done on a  i386 CPU, these are J-series routers. You can also have “Olives” of these as well. Juniper has recently released a new version of Junos for the J-series called Junos-ES (Enhanced Services), which in time all Junos will be Junos-ES. This adds in the functionality of a flow and zone based firewall. This can also be put in vmware. My thinking is that you will have more functionality in the J-series olives because more of the functionality is in the software and does not require another piece of hardware to achieve the same functionality, but I have yet to veriy this.

Also some more good documentation, hooking up an Olive to quagga (software that allows your *nix box to running dynamic routing protocols using ios-like interface).
