Cisco Express Forwarding in Juniper and Foundry ?

[jitenshah18]

I know this is not the right forum to ask but if there is someone who has a experience with Juniper and Foundry can help me.

Is something similar to Cisco Express Forwarding available on Juniper and Foundry switches .

Hello Jiten,

the answer is positive each vendor has his own technologies, but a functional equivalent of CEF is present in Juniper devices according to my direct experience.

Juniper implementation is different and indipendent.

Hope to help

Hey there, buddy.

There's actually no "feature" like CEF in JunOS. When IOS started, it began as a monolithic network operating system. In contrast, Juniper developed JunOS as a modular operating system (I can't really say its micro-kernel, hehe). I haven't looked at IOS-XR, XE and Nexus in detail but Cisco went that route (developing these OSes) to go around the problems with IOS.Look up Ivan's blog post at MPLS: JunOS vs Cisco.

This is a post from x years ago - I got here researching mtrie data structures. Forsome reason I got the "yips" and reading on the weirder stuff is helping me get back my drive in studying and information retention. :)
