Trunk between 6509 RPVST+ and Juniper EX MSTP

[degriffin]

Afternoon -

Any documents / expertise with integrating a Junos EX environment with an existing Cisco 3-tier enterprise? We've aquired a facility that's mostly junos EX devices in a MSTP configuration and our current enterprise is Cisco RPVST+. We have layer 3 to our ISP, but want to bring this site into our environment without having to route through the Internet / firewalls ($$). I've read a few docs on this, would feel better if there was a reference guide or white paper on proper configuration. Any help is appreciated...

I'm not sure what you mean by "proper configuration." As the actual configurations themselves are pretty simple, I'm assuming you're looking for more of a best practices document, which really comes down to understanding how MST operates and interacts with RSTP switches. INE has a pretty good writeup at http://blog.ine.com/2010/02/22/understanding-mstp/

Thanks for the respone - the 'ine' blog is a and helpful. I was looking for a white paper or best practice from Cisco that actually addresses interoperability between different vendors - the blog works.

Thanks again...
