Parameter
Description
Interface Name
The name of the IP interface on which RIP is to be setup. This interface must be
previously configured on the Switch.
IP Address
The IP address corresponding to the Interface Name showing in the field above.
TX Mode
Toggle among Disabled, V1 Only, V1 Compatible, and V2 Only. This entry specifies
which version of the RIP protocol will be used to transmit RIP packets. Disabled
prevents the transmission of RIP packets.
RX Mode
Toggle among Disabled, V1 Only, V2 Only, and V1 or V2. This entry specifies which
version of the RIP protocol will be used to interpret received RIP packets. Disabled
prevents the reception of RIP packets.
Authentication
Toggle between Disabled and Enabled to specify that routers on the network should
us the Password above to authenticate router table exchanges.
Password
A password to be used to authenticate communication between routers on the
network.
State
Toggle between Disabled and Enabled to disable or enable this RIP interface on the
switch.
Interface Metric
A read only field that denotes the Metric value of the current IP Interface setting.
Click Apply to implement changes made.
OSPF
The Open Shortest Path First (OSPF) routing protocol uses a link-state algorithm to determine routes
to network destinations. A “link” is an interface on a router and the “state” is a description of that
interface and its relationship to neighboring routers. The state contains information such as the IP
address, subnet mask, type of network the interface is attached to, other routers attached to the
network, etc. The collection of link-states is then collected in a link-state database that is maintained
by routers running OSPF.
OSPF specifies how routers will communicate to maintain their link-state database and defines several
concepts about the topology of networks that use OSPF.
To limit the extent of link-state update traffic between routers, OSPF defines the concept of Area. All
routers within an area share the exact same link-state database, and a change to this database on one
router triggers an update to the link-state database of all other routers in that area. Routers that have
interfaces connected to more than one area are called Border Routers and take the responsibility of
distributing routing information between areas.
One area is defined as Area 0 or the Backbone. This area is central to the rest of the network in that all
other areas have a connection (through a router) to the backbone. Only routers have connections to the
backbone and OSPF is structured such that routing information changes in other areas will be
introduced into the backbone, and then propagated to the rest of the network.
When constructing a network to use OSPF, it is generally advisable to begin with the backbone (area
0) and work outward
