Definition The Generalized TTL Security Mechanism (GTSM) protects services over the IP layer by checking whether the time to live (TTL) value in the IP header is within a pre-defined range. Purpose If an attacker simulates real OSPF packets and keeps sending them to a device, an interface...
OSPF VPN provides a solution to this problem, as described in the following table. Table 5-11 Routing loop prevention Feature Definition Function DN bit The DN bit is a 1-bit flag used by an OSPF multi-instance process to prevent routing loops. When a PE advertises generated Type 3...
This signal is in the form of a link-local LSA generated by the failed-over router. Neighbor networking devices recognize this signal as a cue that the neighbor relationship with this router should not be reset. As the NSF-capable router receives signals from other routers on th...
OSPF not only routes IP packets based on the destination IP address (given in the packet header), but it also detects topological changes in the AS. After detecting changes, OSPF calculates new, loop-free routes after a short period (known as convergence time) in which routing traffic is ke...

intelligent use of Variable Length Subnet Masks (VLSM) is very useful in IP address allocation. IP multicasting to send link-state updates. better convergence than RIP. allowing better load balancing. allowing a logical definition of networks where routers can be divided into areas. ...
By definition, an ABR has different OSPF interfaces that are attached to different OSPF areas so that it can operate in more than one area. The ABR keeps a copy of the link-state database for each associated area. All routers in an area have identical copies of the autonomous system ...

In this display, these fields show the same type of information as described for the general OSPF virtual link display: Transit Area ID, Neighbor Router, Authentication, and Interface State. This display shows the following additional information: ...
