Steering Traffic in OSPF: Interface Cost
Cost is the metric, OSPF uses to judge a path’s feasibility. Normally to adjust cost on a route you would adjust the cost value on an interface itself. This, however, affects all routes learned via this interface. Unlike the metric in RIP which is determined by hop count and EIGRP’s long mathematical formulated metric, OSPF […]
Tuning OSPF: Bidirectional Forwarding Detection (BFD)
BFD (Bidirectional Forwarding Detection) is a super fast protocol that is able to detect link failures within milliseconds or even microseconds.. All (routing) protocols have some sort of mechanism to detect link failures. OSPF uses hello packets and a dead interval, EIGRP uses hello packets and a holddown timer etc How it works? we discussed […]
Tuning OSPF: area Hierarchy, LSA, and area Type
This OSPF LSA type represents networks from different areas. The ABRs’ responsibility is to take part in various OSPF areas and make sure that networks associated with type 1 LSAs may be accessed in non-originating OSPF areas. How to set up area Hierarchy, LSA, and area Type? we discussed on this webinar series Webinar topic: […]
Stable OSPF: Choosing Network Type
OSPF is a network protocol that requires hierarchical design. The concept of area is used in an OSPF network. From a hierarchical perspective, areas on an OSPF network are classified into backbone and non-backbone areas. How to choose network type to get stable OSPF? we discussed on this webinar series Webinar topic: Stable OSPF: Choosing […]
