Route Redistribution Settings - D-Link xStack DES-3800 Series User Manual

Route Redistribution Settings

Route redistribution allows routers on the network, which are
running different routing protocols to exchange routing
information. This is accomplished by comparing the routes
stored in the various routers routing tables and assigning
appropriate metrics. This information is then exchanged among
the various routers according to the individual routers current
routing protocol. The Switch can redistribute routing
information between the OSPF and RIP routing protocols to all
routers on the network that are running OSPF or RIP. Routing
information entered into the Static Routing Table on the local
xStack switch is also redistributed.
Routing information source − OSPF and the Static Route table.
Routing information will be redistributed to RIP. The following
table lists the allowed values for the routing metrics and the
types (or forms) of the routing information that will be
redistributed.
Entering the Type combination − internal type_1 type_2 is functionally equivalent to all. Entering the combination type_1 type_2
is functionally equivalent to external. Entering the combination internal external is functionally equivalent to all.
Entering the metric 0 specifies transparency.
This window will redistribute routing information between the OSPF and RIP routing protocols to all routers on the network that
are running OSPF or RIP. To access the Route Redistribution Settings window, go to > L3 Features > Route Redistribution
Settings:
The following parameters may be set or viewed:
Parameter Description
Dst. Protocol Allows for the selection of the protocol for the destination device. Choose between RIP and
OSPF.
Src. Protocol Allows for the selection of the protocol for the source device. Choose between RIP, OSPF, Static
and Local.
Type Allows for the selection of one of six methods of calculating the metric value. The user may
choose between All, Internal, External, ExtType1, ExtType2, Inter-E1, Inter-E2. See the table
above for available metric value types for each source protocol.
Metric Allows the entry of an OSPF interface cost. This is analogous to a Hop Count in the RIP routing
protocol. The user may specify a cost between 0 and 16.
