Configuring OSPF Interface Cost Free CCNA Workbook
Routing . Routing is the process of getting information packets where they need to go. Routing is a surprisingly complicated task, and there are a number of different algorithms used to find the shortest route between two points.... BGP is a protocol which performs routing information exchange among routers to determine the optimal paths for the traffic flow. A BGP router forms a neighbor relationship by connecting to its neighbors and exchanging the routes, once the connection is established.
Route Selection in Cisco Routers Cisco
9/09/2013 · A particular destination can be advertised to the router by various routing protocols, for example static route, BGP, OSPF, etc. In this case, the selection of the best route is based on the “administrative distance” where the lowest value is preferred....In voice telecommunications, least-cost routing (LCR) is the process of selecting the path of outbound communications traffic based on cost. Within a telecoms carrier, an LCR team might periodically (monthly, weekly or even daily) choose between routes from several or even hundreds of carriers for destinations across the world.
As you might have learned in CCNA or CCNP, OSPF will use cost as the metric to choose the shortest path for each destination, this is true but it’s not entirely correct. windows how to get to command prompt Given two separate routes to the same destination, the router chooses the route with the lowest AD. When a router has the choice of a static route and an EIGRP route, the static route takes precedence. Similarly, a directly connected route with an AD of 0 takes precedence over a static route ….

- 27/02/2015 · Just to give a little background on how the default OSPF costs are determined by the router (in case you don't know): If you issue show ip ospf interface on each of your routers, you'll see what the cost is on each interface.
- BGP is a protocol which performs routing information exchange among routers to determine the optimal paths for the traffic flow. A BGP router forms a neighbor relationship by connecting to its neighbors and exchanging the routes, once the connection is established.
- for both routes, the router will load balance between both paths. If a router receives a RIP and an OSPF route to the same network, it will use Administrative Distance to determine which routing path to choose.
- Some other router will calculate the cost to these networks by summing the exit interface costs to 172.16.25.1, and then adding 180. (Had the metric-type been E2 (external type 2), the other router would not include the interface costs, and would consider the route to have a metric of 180.)
