Routing
AS/Tag—Indicates the Process ID of the redistributed protocol. A Positive Integer will indicate the
process id of the redistributed protocol; a character string will indicate the ISO routing area tag.
IS-IS Route Level—Specifies the routing level of ISIS Protocol.
Redistribution Metric—Displays the metric used for redistributed routes for this address family.

OSPF Management

Open Shortest Path First (OSPF) is a TCP/IP internet routing protocol. OSPF is classified as an Interior
Gateway Protocol (IGP). This means that it distributes routing information between routers belonging
to a single Autonomous System (AS). The OSPF protocol is based on link-state or SPF technology based
on Dijkstra's algorithm. Each OSPF router maintains an identical database describing the Autonomous
System's topology. From this database, a routing table is calculated by constructing a shortest-path tree.
OSPF has been designed expressly for the TCP/IP internet environment, including explicit support for
Classless Inter-Domain Routing (CIDR) and the tagging of externally-derived routing information.
OSPF also provides for the authentication of routing updates, Variable Length Subnet Masks (VLSM),
route summarization and utilizes IP multicast when sending/receiving the updates. OSPF recalculates
routes quickly in the face of topological changes, utilizing a minimum of routing protocol traffic.

OSPF Configuration

The OSPF Configuration window allows the user to enable or remove OSPF configurations on a router.
The OSPF configuration section covers the following topics:
