1. if an eigrp router which have no downstream neigbor (leaf router ) receives a query and if the router dont have a feasible successor,then it would give an eigrp reply with the route as unreachable.
(a)will the router then remove the route from its routing table/topology table immediately??
(b)it keeps the route in routing table/topology table and sends a reply as unreachable ,and then the router which originated the query, after receiving all the reply for the query and finding that its not reachable will remove from its tables and will send an update stating that the route is unreachable to its neighbor,and hence the leaf router removes it from the table.
which of the abv happens or is it something else happens??
if (a) happens ,eigrp update is said to be also send when a link fail(or route not reachable).if the other router learns the unreachable routes as on case (a),then why update needed to be send..??
2.what are the contents of an eigrp query/reply pck(know that both have a type code of 3 and 4 respc)??
3.eigrp updates are said to be bounded,ie it sends only to affected neighbors.how it comes to know who all will be affected by routers..??
