How ospf avoid loops
Nettet12. des. 2014 · Instead, if we make area 0 a backbone, and say areas can only receive routes from the backbone, then there is only one possible path to area 2 -- through the … NettetI think you are just mixing things up. Loop-prevention with routing-protocols is existing to avoid the situation from even happening. Meaning - in a sane network there should be no loops possible. To avoid this situation the routing-protocols follow a strict-set of rules so that this cannot happen.

Nettet13. mar. 2024 · R1 connects to R2, and R2 connects to R3, and R3 connects to R4, and R4 has a connection to R2. For simplicity let us assume that the EIGRP metric to get across most of the links is 100, but the link between R4 and R2 is a slow serial link with metric of 1000. So R1 advertises 10.1.1.0 to R2. R2 calculates its feasible distance to … Nettetareas, loop prevention should be based on distance-vector principles. There are three main rules of generating and receiving inter-area routes (type-3 LSAs) in OSPF that …
NettetWhen there is more than one redistribution point between OSPF domains, routing loops can easily occur. To prevent routing loops, prefixes that belong to a domain should not be redistributed back to the same domain. Also, the administrative distances of the OSPF processes should be set correctly. These five methods have been proposed in this ...
