Operation Manual - Routing Protocol
Quidway S6500 Series Ethernet Switches
3.2.11 Configuring Split Horizon
Split horizon means that the route received via an interface will not be sent via this
interface again. The split horizon is necessary for reducing routing loop. But in some
special cases, split horizon must be disabled so as to get correct advertising at the cost
of efficiency. Disabling the split horizon has no effect on the p2p connected links but is
applicable on the Ethernet.
Perform the following configuration in Interface view:
Table 3-11 Configuring Split Horizon
Enable split horizon
Disable split horizon
By default, split horizon of the interface is enabled.
3.2.12 Configuring RIP to Import Routes of Other Protocols
RIP allows users to import the route information of other protocols into the routing table.
RIP can import the routes of Direct, Static, OSPF, IS-IS and BGP, etc.
Perform the following configurations in RIP view.
Table 3-12 Configuring RIP to import Routes of Other Protocols
Configure RIP to import routes of other protocols
Cancel the imported routing information of other
protocols
By default, RIP does not import the route information of other protocol.
3.2.13 Configuring Default Cost for the Imported Route
When using the import-route command to import the routes of other protocols, you
can specify the cost of them. If you do not specify the cost of the imported route, RIP will
set it to the default cost, specified by the default cost parameter.
Perform the following configurations in RIP view.
