</div>Why OLSRd does not do this? For example we have everywhere the same<br>
configuration. So it could assume that originators' configuration is<br>
the same as its own and check all this stuff and print some warning to<br>
log or something.<br></blockquote><div><br></div><div>so they vtime thing is already a patch against txtinfo, which is not enabled by default,..</div><div><br>the vtime patch was made for finding/confirming a misconfiguration, of course its`improveable,..</div>

<div><br></div><div>a bit better would be to have a counter inceased every time something goes under 1/2 of its vtime, and report only nodes that increased this counter over certain thresholds, but do not not report ones that go directly into timing out (as it probably really went down,..)</div>
<div><br></div><div>"reducing above idea to the max" would be to check the old vtime, when a new packet comes in, if it was less than 1/2 of the new vtime, just print a warning, this requires no new datafields, just 1 LOC for each message type,..</div>

<div><br></div><div>but if u don`t care, just set a vtime of virtually infinite for everything on every node, but please do not whine if u don like the results,.. *G</div><div><br></div><div>btw: setting vtime to infinite is not the same as having the last route forever.</div>
