Karten in diesem Stapel (8)
- 1Autonomous SystemA group of networks and routers controlled by a single administrative
authority - 2Autonomous System ConceptEach collection of networks and routers managed by one administrative authority is considered to be a single autonomous system that is free to choose an internal routing architecture and protocols.
- 3Practical Limit on Group SizeIt is safe to allow up to a dozen routers to participate in a single routing information protocol across a wide area network;
Approximately five times as many can safely participate across a set of local area networks. - 4Exterior Gateway Protocol (EGP)Any protocol designed to exchange routing and reachability information among autonomous systems on the Internet
- 5EGP solves two problems:Allows router outside a group to advertise networks hidden in another autonomous system
Allows router outside a group to learn destinations in the group - 6Border Gateway Protocol (BGP)Basically the only EGP still in existence
Each AS designates a border router to speak on its behalf
Two border routers become BGP peers - 7Key characteristics of BGPProvides inter-autonomous system communication
Propagates reachability information
Follows next-hop paradigm
Provides support for policies
Sends path information
Permits incremental updates
Allows route aggregation
Allows authentication - 8Key restriction on an EGPAn exterior gateway protocol does not communicate or interpret distance metrics, even if metrics are available.
