hi, we use PBR on our RXs. it works ok. all hardware switched at 10Gbps. it's easy to set up - ACL, plus route map to set next-hop. we put our route-maps on ve interfaces.
it defaults to *not* matching, so if traffic doesn't match your acl it won't have its next-hop adjusted. you don't need a deny at the end. dunno about documentation... I find it pretty difficult to find anything other than what's in the manuals, or on this mailing list (or in japanese). only thing to be aware of is your CAM partitioning - if your ACL reaches not-that-many entries (keeping in mind a single ACL line can render to several entries in the CAM) you'll find your CAM partition filling up and the only way to adjust the partition size (on an RX, anyway) is to set and reboot the switch... if you're thinking about setting up a big, complex ACL .. think carefully about it and make sure you'll have space in your CAM before you go live. you're not crazy for trying. it's simple and it seems to work. for us. my only advice is - *only* use it where *necessary* - PBR can be a bastard to troubleshoot when it gets complicated :-) HTH Nick On Fri, Feb 5, 2010 at 7:49 PM, seph <[email protected]> wrote: > As I continue to tinker with my network, I'm increasing interesting in > PBR.
