What does a street sign like this tell you? How far (distance) Which way (direction) Distance vector Routes are advertised as vectors of distance and direction. BGP is the only EGP that is used today.Įxterior Gateway Protocols Interior Gateway Protocols Distance Vector Link State Path Vector Distance Vector Routing Protocols Link State Routing Protocols Path Vector RIPv2 EIGRP OSPFv2 IS-IS BGP-4 RIPng EIGRP for IPv6 OSPFv3 * IS-IS for IPv6 BGP-4 for IPv6 or MP-BGP IPv4 IPv6 * OSPFv3 supports routing both IPv4 and IPv6. RIP EIGRP OSPF IS-IS Exterior Gateway Protocols (EGP): Used to exchange routes between different ASs. Input (network) requirements Size of the network (scalability) Vendor interoperability Familiarity What’s currently being used Protocol characteristics: IGP or EGP Type of routing algorithm Speed of convergence Scalability SummarizationĨ IGP versus EGP Interior Gateway Protocols (IGP): These are used within the organization, and they exchange the routes within an AS. OSPF or EIGRP Multiple routing protocols (IGP and BGP) are used when the organization is multihomed to two or more ISPs for Internet connectivity. Routing protocols provide: Network reachability between routers Dynamically adapt to network changes Best practice that you use one IP (IGP) routing protocol throughout the enterprise. Usually scalable hierarchical model Access layer Distribution layer Core layerĮnterprise Edge: Provides: Access to the Internet Access to the same network services as users at the main site. 1 Basic Network and Routing ConceptsĬonnecting Remote Locations Static Routing PPP Overview Frame Relay Overview Types of VPNs MPLS Overview Virtual Routing and Forwarding (VRF) and Cisco EVN VPN Overview Tunnels Characteristics of a Secure VPN DMVPN and NHRP Concepts IPv6 Overview GUA Link-local address ICMPv6 ND Implementing RIPng Differentiating Routing Protocols Enterprise Network Architecture Routing Protocols Understanding Network Technologies Traffic Types Network Types and Frame Relay Challenges TCP/IP IPv4 and IPv6 Headers TCP MSS Path MTU Discovery TCP BDP TCP Starvation ICMP Redirect Asymmetric RoutingĪ high-level overview of a typical enterprise network, it can be divided into two major areas: Enterprise Campus Enterprise EdgeĮnterprise Campus: Provides access to the network communications services and resources to end users and devices.
