<meta name='description' content='This scene demonstrates that even though a minimal interference secondary route has been identified in case of link failure, (a) both routes may be invalid due to an overlap at a critical link, and (b) some reasonable third path may exist to route packets. Note that the hop count is larger (by 1) for each successive route. By pushing the right rear button, the critical link that overlaps the primary and secondary route will turn red opaque.'/>
