As dynamic routing protocols, BGP and OSPF are widely used on live networks. Mutual route import between BGP and OSPF processes is often involved in networking solutions. If no correct routing policies are configured on the devices where routes are mutua

Distance-vector routing protocols use the routing update timer to propagate routing updates. If the value of this timer is not the same on all routers, routing loops may occur. In other words, routing loops may occur when all routers do not broadcast routing updates simultaneously. When a loop...
OSPF is widely used on live networks. OSPF multiprocess route import is often involved in networking solutions. If no routing policies are configured or routing policies are configured improperly on the devices that perform mutual route import between OSPF processes, Layer 3 routing loops may occur ...
BGP is the latest and a popularly used routing protocol in the networking world. It is built on the foundations of EGP and is classified as a distance path vector protocol. BGP has two variations based on how it is used. Internal BGP: IBGP enables network communication between routers within...
EIGRP has a lower administrative distance than RIP (90 versus 120); therefore, the EIGRP route is used in the routing table. Now there is a potential routing loop. Even if split horizon, or any other feature meant to help prevent routing loops is used, there is still a convergence ...
BGP uses a path-vector routing algorithm to exchange network reachability information with other BGP-speaking networking devices. Network reachability information is exchanged between BGP peers in routing updates. Network reachability information contains the network number, path-specific attributes...
(DNS), routing protocols such asOSPFand their respective route tables, which can cause various forms of networking irregularities such as temporary routing loops and unnecessary network failovers. The use of defensive techniques such asaccess control lists(ACLs) control what traffic types are allowed...
In VANET, ML techniques, especially RL, try to make vehicles take self-decisions for networking operations such as routing [11,12]. The agent must obtain knowledge in relation to the environment dynamics based on the collected data to find the most suitable action and achieve a certain purpose...
Poison reverseis another stability feature that assists with routing loops. A poison reverse is a way for a gateway node to tell its neighbor gateways that one of the gateways is no longer connected. The notifying gateway sets the number of hops to the unconnected gateway to 16, a number ...
