What are Passive and Acitve route states?
An operational route’s normal condition is known as ‘Passive State’. The router
will not seek to replace a lost route, when it is in the normal condition. At
the time of a router is aware of a route in the route table becomes invalid,
DUAL is run on the topology table, and a search for feasible successor is
A router states is said to be ‘Active State’, when the feasible successor is not
found. The DUAL diffuses the computation by sending the query packets to some
other routers as part of attempting to find a replacement path to the network.
A route is considered as ‘stuck in active’ when the replies to queries of an
active route are not received.
