How do I find the previous version, 6.32.4 bugfix?  I want to be sure it is the 
correct download.

Also, any issues downgrading from 6.36?

we've been recommending RouterOS version 6.32.4 bugfix to all of our clients as 
the most "stable" version for BGP/OSPF/MPLS as we have run into issues with 
6.35 and 6.36 with all of those protocols. Unless there is a specific feature 
or fix you need in later versions of code, I wouldn't go beyond 6.32.4 until 
they have another stable bugfix version.

Thanks,

FWIW, I had similar problems with OSPF while upgrading our equipment from 
6.34.6 to 6.36.  When one side of a link is the earlier version, and the other 
the later version, OSPF wouldn't propagate routes at all, until the other end 
was upgraded as well.  After that, the network remained unstable because the 
routing tables on some of the routers are now changing back & forth between two 
different sets of routes, several times a minute.  I'm still trying to pinpoint 
the problem.  It seems most common when there are two routes between A and B, 
one of which is a PPTP tunnel over a third party network.  It worked well 
enough prior to 6.36, but it's hard to tell whether the problems I'm seeing now 
are the result of introducing a bug, or fixing one.
