3Com Switch 8800 Configuration Guide Chapter 18 RIP Configuration
18-5
Table 18-4 Configure Split Horizon
Operation Command
Enable split horizon rip split-horizon
Disable split horizon undo rip split-horizon
By default, split horizon of the interface is enabled.
18.2.5 Setting Additional Routing Metric Additional routing metric is the input or output routing metric added to an RIP route. It
does not change the metric value of the route in the routing table, but adds a specified
metric value when the interface receives or sends a route.
Perform the following configuration in interface view.
Table 18-5 Set additional routing metric
Operation Command
Set the additional routing metric of the route when the
interface receives an RIP packet rip metricin value
Disable the additional routing metric of the route when
the interface receives an RIP packet undo rip metricin
Set the additional routing metric of the route when the
interface sends an RIP packet rip metricout value
Disable the additional routing metric of the route when
the interface sends an RIP packet undo rip metricout
By default, the additional routing metric added to the route when RIP sends a packet is
1. The additional routing metric when RIP receives the packet is 0 by default.
Note:
The metricout configuration takes effect only on the RIP routes learnt by the router and
RIP routes generated by the router itself. That is, it has no effect on the routes imported
to RIP by other routing protocols.
RIP allows users to import the route information of other protocols into the RIP routing
table.
RIP can import the routes of Direct, Static, OSPF, IS-IS and BGP, etc.
