LECTURE ROUTING PROTOCOLS - CHAPTER 1: ROUTING CONCEPTS

ƒ R1 receives the stream of encoded bits on its interface. The bits are decoded and passed up to Layer 2, where R1 decapsulates the frame. The router examines the destination address of the data link frame to determine if it matches the receiving interface, including a broadcast or

After receiving the navigation messages, a GPS receiver can determine its position and roaming velocity. To determine the receiver’s lon[r]

This method is also how routers advertise a network as unreachable. Whether it is a poisoned reverse route, a network that has failed, or a network beyond the maximum network diameter of 15 hops, a router will recognize any 16-hop route as unreachable.
Setting a maximum hop count of 15 helps so[r]

ties to a router. Each port is connected to a circuit board that is attached to the router’s mother- board. Thus, the motherboard actually provides the interconnectivity among multiple networks. The network administrator must configure each interface via the router’s console. Configura- tion includes[r]

Step 5: Examine the routing table on the R1 router.
Both R1 and R3 are configured with interfaces on a discontiguous network, 172.30.0.0. The 172.30.0.0 subnets are physically and logically divided by at least one other classful or major network—in this case, the two serial networks 209.[r]

The research object of the thesis focuses on the load balancing routing algorithms and QoT aware routing in MANET. The research scope of the thesis is the DSR and AODV routing protocols.

IGRP
Like RIP, Interior Gateway Routing Protocol (IGRP) is a distance vector routing pro- tocol. Unlike RIP, IGRP is a Cisco-proprietary protocol rather than a standards-based protocol. While remaining very simple to implement, IGRP is a more complex routing protocol than[r]
