A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS , [ 1 ] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF .
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the ...
To configure IP addresses on interfaces, masks start with 255 and have the large values on the left side: for example, IP address 203.0.113.129 with a 255.255.255.224 mask. Masks for IP ACLs are the reverse: for example, mask 0.0.0.255. This is sometimes called an inverse mask or a wildcard mask. When the value of the mask is broken down into ...

Mama June Shannon is opening up about the current living situation of Anna "Chickadee" Cardwell's daughter Kylee following her mom's death last December. In an exclusive interview with PEOPLE, the ...
The link-state advertisement (LSA) is a basic communication means of the OSPF routing protocol for the Internet Protocol (IP). It communicates the router's local routing topology to all other local routers in the same OSPF area.

i want to ask you that if why we have the wildcard mask in the ospf .is it use any security. The wildcard mask is a legacy technology from the days when ACLs were in common use and NAND gates were faster and easier to program than AND gates.
