in most cases we rather not change defaults (yes, I know, there have been too many cases where we did, incl. without notice), and in some smaller-scaled untuned OSPF network scenarios the RIB purge actually has some benefits (could take up a floating static ~5 secs quicker, for example in a spoke node with a backup). so changing the default has some implications. I agree that it should be default these days (it is in XR & NX-OS), but so should be lower spf/lsa-throttle timers. oli _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
