45.1.3.9 Configuring the Maximum Number of Routes
By default, the local RIP routing table contains up to 1024 routes. When the route number exceeds the
maximum number, you cannot add new routes to the routing table. At the same time, the system notifies you
that the route number has already reached the maximum number set for the routing table.Run the following
command in switch configuration mode to configure the maximum number of routes for the local RIP routing
table:
Command Purpose
maximum-countnumber
Configures the maximum number of
routes for the local RIP routing table.
no maximum-count
Resumes the default maximum number
of routes.
45.1.3.10 Aactivating or Forbidding Horizon Split
Normally, the switch that connects to the broadcast IP network and adopts the distance vector routing protocol
adopts the horizon split to reduce the possibility of the routing loop. The information about the routing loop of
horizon split declares itself to the interface that receives the routing information. In this way, the
communication among multiple routing switches is improved, especially when the loop breaks. However, it is
not so good as to the non-broadcast network. At this time, you may forbid the horizon split.
If the assistant IP address is configured on the interface and the horizon split is activated, the source IP
address of the routing update may not conclude all assistant addresses. The source IP address of one routing
update contains only one network number.
Run the following commands in VLAN configuration mode to activate or forbid the horizon split.
Command Purpose
ip rip split-horizon
Activates the horizon split.
no ip rip split-horizon
Forbids the horizon split.
By default, the horizon split is activated on the point-to-point interface; the point-to-multiple interface is
forbidden.
Foe details, refer to the section “Horizon Split Example”.
In normal case, do not change the default configuration unless you are sure that the
programs need to change states. Remember that if the horizon split is forbidden in
a serial port that connects a packet switching network, you must forbid the horizon
split in the switches in relative multiple-program group of a network.
45.1.3.11 Monitoring and Maintaining RIP
Monitoring and maintaining RIP needs to display network statistics information, such as RIP parameter
configuration, real-time network track. These information help you judge the network usage, solve network
problem and the reachabilitiy of network nodes.
Run the following commands in management mode to display all routing statistics information:
