routing loop

routing loop

A network problem in which packets continue to be routed in an endless circle. It is caused by a router or line failure, and the notification of the downed link has not yet reached all the other routers. It can also occur over time due to normal growth or when networks are merged together. See route poisoning.

Lines 59 to 66 show that when the strategy disables the Split Horizon characteristic, at moment t=60 a routing loop arises; this is because R1 aims towards R2 and at the same time R2 aims towards R1 in order to reach the 2001:0:4::/64 destination.
In terms of routing loop prevention, when contrasting the simulations used by the Poison Reverse strategies, Split Horizon and disabled Split Horizon, it is found that the most helpful one for said purpose is inverse poisoning, the intermediate one is Split Horizon and the worst is the one which disables Split Horizon.
Furthermore, during this time period routing loops can arise, depending on the Split Horizon strategy that is used for the simulation.

The maximum number of hop count is to solve the routing loops problem.
If incorrectly configured, it can cause network instability and routing loops, hence it is a common practice to ignore this ability.
An adversary composes packets with purposely introduced routing loops.
VIP is free from routing loops with all packets, except for the first packet, traversing the optimum route, and
Consequently, as long as the routing control in the IP layer is free from routing loops, VIP will never exhibit routing loops.
