If one end has locators A and B, and the other end has C and D ... then unless you are multipathing you will use a single pair, e.g. A-C, while A-D and B-C are not being used, just checked for liveness in case a need arises. _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
