After watching the mpls sham link video from Brian, it made me wonder something. He had a problem where the same route was learnt from two different neighbors, who were both advertising the route as the same type of LSA (Type 3), however one neighbor was in area0 and the other was in area78. So even though the metric was lower via area 78, the path that was preferred was via area0. This got me thinking. If we had this same scenario again but the neighbors were in area 77 and 78 (i.e. not area 0), would the lower area number take preference (i.e. the path via area 77 regardless of metric) or could we use metric to influence the decision?
Just trying to work out if this path selection is only applicable when using area0.
Thanks,
Stephen
