The actual amount of memory required in a BGP router depends on the amount of BGP information exchanged with other BGP speakers and the way in which the particular router stores BGP information. The router may have to keep more than one copy of a route, so it can manage different policies for route advertising and acceptance to a specific ...
The no auto-summary command prevents automatic route summarization on classful boundaries, which would otherwise result in routing loops in discontiguous networks. Router# configure terminal Router(config)# router eigrp 1 Router (config-router)# network 10.201.96.0 0.0.15.255 Router (config-router)# no auto-summary Router (config-router)# exit
An autonomous system boundary router is a router that is connected by using more than one routing protocol and that exchanges routing information with routers autonomous systems. ASBRs typically also run an exterior routing protocol (e.g., BGP), or use static routes, or both.
RIPv1 is not suitable for large networks as it limits the number of hops to 15. This hop limit was introduced to avoid routing loops, but also means that networks that are connected through more than 15 routers are unreachable. [3] The distance-vector protocol designed for use in wide area networks (WANs) is the Border Gateway Protocol (BGP).
The letter "S" indicates that the route is a static route that has, for all intents and purposes, been added manually to the router process by the administrator and installed into the routing table. Router#enable Router#configure terminal Router(config)#ip route 1.1.1.0 255.255.255.0 fastEthernet 0/0 Router(config)#do show ip route
Multiprotocol BGP is also widely deployed in case of MPLS L3 VPN, to exchange VPN labels learned for the routes from the customer sites over the MPLS network, in order to distinguish between different customer sites when the traffic from the other customer sites comes to the provider edge router (PE router) for routing.
RouteViews is a project founded by the Advanced Network Technology Center at the University of Oregon to allow Internet users to view global Border Gateway Protocol routing information from the perspective of other locations around the internet. Originally created to help Internet Service Providers determine how their network prefixes were ...
Each routing protocol contains loop-avoidance mechanisms, but the information needed for loops to be avoided is lost when routes are redistributed. For example, a distance-vector routing protocol may prevent loops by the "split-horizon" rule; that is to say, if a router learns a route from a particular interface it will not re-advertise the ...
