Defeating Independence

The routing table entries within an rvrd process operate as independent pathways; that is, data does not flow directly between routing table entries within a routing daemon process instance.

Nonetheless, data can flow indirectly by way of a mutual neighbor. In Mutual Neighbors Merge Routes, notice that adding a neighbor link between M and T would merge the route connecting networks A, B and C, with the otherwise disjoint route connecting X and Y (defeating their independence). Use caution when altering a network of routing daemons.
