If the router detects that a network is unreachable, the timer is started. The router will then wait a preset number of seconds until the network stabilizes. When the timer expires, the router will begin receiving its routing updates from other routers. For example, in RIP, the default holddown timer is set to 180 seconds.
This timer must be set to a higher value than the invalid timer. [13] Holddown Timer The hold-down timer is started per route entry, when the hop count is changing from lower value to higher value. This allows the route to get stabilized. During this time no update can be done to that routing entry. This is not part of the RFC 1058.
RIP is a routing protocol that converges so slowly that even a network of a few routers can take a couple of minutes to converge. In case of a new route being advertised, triggered updates can speed up RIP's convergence but to flush a route that previously existed takes longer due to the holddown timers in use. OSPF is an example of a fast ...
whereas Juniper implementation has different definitions for hold-down ( However, the expired route is retained in the routing table for a specified period so that neighbors can be notified that the route has been dropped. This time period is set by configuring the hold-down timer.
IGRP was created in part to overcome the limitations of RIP (maximum hop count of only 15, and a single routing metric) when used within large networks. IGRP supports multiple metrics for each route, including bandwidth , delay , load , and reliability ; to compare two routes these metrics are combined into a single metric, using a formula ...

Route poisoning is a method to prevent a router from sending packets through a route that has become invalid within computer networks. Distance-vector routing protocols in computer networks use route poisoning to indicate to other routers that a route is no longer reachable and should not be considered from their routing tables.
It pays to have multiple interviews going at the same time. This is one of many reasons I encourage all job seekers to take interviews that seem interesting to them. Even if they feel like one of ...
