Re: [j-nsp] MX480 Filter based forwarding performance

Hi, short answer: it depends :-) It is done in hardware, and for "sane" filters will work at line rate (e.g. I have built a setup where few hundred GBit/s are forwarded using FBF on MX960 with multiple MPC7E). However, if you use lots of exotic match conditions and/or excessively long filter

[j-nsp] MX480 Filter based forwarding performance

I am hoping someone can provide a good link to FBF performance, is it handled by the PFE in hardware or is it handled in software, limitations if any? I have a design that is using FBF extensively, currently we are not routing much traffic but that could change soon. thanks in advance, Mike
