k2s Posted October 17, 2011 Author Report Posted October 17, 2011 Ok Guys I am starting the lecture...... Some general functions of router: 1. Learn routing information about IP subnets from other neighboring routers. 2. Advertise routing information about IP subnets to other neighboring routers. 3. If more than one possible route exists to reach one subnet, pick the best route based on a metric. 4. If the network topology changes—for example, a link fails—react by advertising that some routes have failed, and pick a new currently best route. (This process is called convergence.)

[img]http://i56.tinypic.com/2rcpips.png[/img] [/quote] Both R1 and R3 learn about a route to subnet 172.16.3.0/24 from R2 (function 1). After R3 learns about the route to 172.16.3.0/24 from R2, R3 advertises that route to R1 (function 2). Then R1 must make a decision about the two routes it learned about for reaching subnet 172.16.3.0/24: one with metric 1 from R2, and one with metric 2 from R3. R1 chooses the lower metric route through R2 (function 3) Quote

k2s Posted October 17, 2011 Author Report Posted October 17, 2011 Types of Routing Protocols: Interior and Exterior Routing Protocols IP routing protocols fall into one of two major categories: Interior Gateway Protocols (IGP) or Exterior Gateway Protocols (EGP). The definitions of each are as follows: ■ IGP: A routing protocol that was designed and intended for use inside a single autonomous system (AS) ■ EGP: A routing protocol that was designed and intended for use between different autonomous systems NOTE The terms IGP and EGP include the word gateway because routers used to be called gateways.

k2s Posted October 17, 2011 Author Report Posted October 17, 2011 Below figure clears shows....where we use IGP(EIGRP, OSPF, RIP, IS-IS) & where we use EGP(BGP) [img]http://i54.tinypic.com/2it4u38.png[/img] Quote
k2s Posted October 17, 2011 Author Report Posted October 17, 2011 Three main branches of routing protocol algorithms exist for IGP routing protocols: ■ Distance vector (sometimes called Bellman-Ford after its creators) ■ Link-state ■ Balanced hybrid (sometimes called enhanced distance vector) IGP Metric Description RIP-1, RIP-2 Hop count The number of routers (hops) between a router and the destination subnet. OSPF Cost The sum of all interface cost settings for all links in a route, with the cost defaulting to be based on interface bandwidth. EIGRP Composite of Calculated based on the route’s slowest link and the bandwidth and delay cumulative delay associated with each interface in the route. Quote
k2s Posted October 17, 2011 Author Report Posted October 17, 2011 [img]http://i55.tinypic.com/29o5xcl.png[/img] Router B’s RIP route to 10.1.1.0 points through Router A because that route has a lower hop count (1) than the route through Router C (2). However, in the lower half of the figure, Router B chooses the two-hop route through Router C when using EIGRP because the bandwidths of the two links in the route are much faster (better) than that of the single-hop route. Note that so that EIGRP would make the right choice, the engineer correctly configured the interface bandwidth to match the actual link speeds, thereby allowing EIGRP to choose the faster route.
