RouterJockey : Using Discontiguous Wildcard Masks in ACLs

Sat, 13 Jul 2013 18:58:46 +0000

Thank you for that. This stuff is far easier when you're working on paper vs trying to do it in a text editor + html formatting :) I've updated the post to fix my XOR / AND maths.

RouterJockey : Using Discontiguous Wildcard Masks in ACLs

Wed, 16 Nov 2011 18:38:54 +0000

Not sure what I was thinking when I said 1 xor 0 = 1 xor 1 = 1... but that is not correct. Just proves that we're all human, right? BUT, when you're setting up a discontiguous mask for 3 or more IP addresses, you need to forget XOR, and simply use your own logic. Is the bit significant or not... in the case of comparing 1, 0, 1.. the bit is NOT significant, thus it will be set to 1... Maybe it would be best if I rewrote this article to better explain the logic.

No problem Keith, this was from a Linux server, but it could've just as easily been from a Mac, or a Windows desktop running Cygwin.

My apologies, meeting so many great people that week has led to a bit of name jumble... Thank you so much for having us out, we certainly enjoyed learning more from everyone at NFD2.

Unfortunately I wasn't able to find a way to do that... I ended up having to add some static routes in my network to get to the P2P address on the device I was attempting to fix.

The problem is that when you're dealing with multiple values, you can't treat it as a true XOR.. as a true XOR is between 2 values and the order of operations would affect the output. (101=1 110=0, if that makes sense) In this case, you're looking at a significant, or don't care bit. Thus, if you have 101, your bit has to bet set to 1, because you don't care about this value. It changes between the 3 IPs you're checking against. Does that make sense?

You're absolutely correct, not sure how that made it in there, but I've updated the post now.

Unless you write a full blown TCL script, I don't think there is going to be a way to do this within EEM. I'm not up to speed on TCL programming as of yet, so unfortunately I'm not sure where to point you for additional information.

It really depends on what exactly you're trying to do, and if there is a way to insert regex in that function. If you can give me more detail about what you're trying to accomplish, I'd be more than happy to try and help you out.

Yeah... My birthday was a complete waste... I left the hotel at 5am, didn't get hom until after 7pm... We brought our bags in, had dinner, and I went to bed.. LOL

Nope.. too salty for me.. I'd love to get a new Fluke CableIQ and maybe a Fiber QuickMap, or even a OptiFiber, but they're just too much $$ for me to justify...

You can most certainly use 1-Gig Copper for your peer keep-alive.. that's actually how I'm running in production right now. Your peer-links most definitely need to be 10g though..
