Interior gateway protocol. Used between routers within the same autonomous system.
IGP
An independent, configurable entity, typically a protocol.
instance
IP tunnels
Internet Protocol version 4.
IPv4
K
A special message sent between routing peers to verify and maintain communications between the pair.
keepalive
L
An arbitrary number configured on an OSPF interface which is in shortest path first calculations.
link cost
Shares information about a link, link cost to neighboring routers.
link-state
See LSA.
link-state
advertisement
Link-state advertisement. An OSPF message to share information on the operational state of a link, link
LSA
cost, and other OSPF neighbor information.
OSPF database of all LSAs received. OSPF uses this database to calculate the best path to each
link-state database
destination in the network.
The time that OSPF floods the network with LSAs to ensure all OSPF routers have the same
link-state refresh
information.
The degree to which a network resource, such as a router, is busy.
load
The distribution of network traffic across multiple paths to a given destination.
load balancing
M
A one-way hash applied to a message using a shared password and appended to the message to
message digest
authenticate the message and ensure the message has not been altered in transit.
A standard of measurement, such as the path bandwidth, that is used by routing algorithms to determine
metric
the optimal path to a destination.
A cryptographic construction that is calculated based on an authentication key and the original message
MD5 authentication
and sent along with the message to the destination. Allows the destination to determine the authenticity
digest
of the sender and guarantees that the message has not been tampered with during transmission.
Maximum transmission unit. The largest packet size that a network link will transmit without
MTU
fragmentation.
