IP Routing Features 
Configuring RIP 
Parameter  Description  Default 
IP address  The routes that a routing switch learns or advertises  The routing switch 
can be controlled.  learns and 
advertises all RIP 
routes on all RIP 
interfaces 
loop  The method the routing switch uses to prevent routing 
Poison reverse 
prevention  loops caused by advertising a route on the same 
interface as the one on which the routing switch 
learned the route. 
•  Split horizon - the routing switch does not 
advertise a route on the same interface as the one 
on which the routing switch learned the route. 
•  Poison reverse - the routing switch assigns a cost 
of 16 (“infinite” or “unreachable”) to a route before 
advertising it on the same interface as the one on 
which the routing switch learned the route. 
receive  Define the RIP version for incoming packets  V2-only 
send  Define the RIP version for outgoing packets  V2-only 
Configuring RIP Parameters 
Use the following procedures to configure RIP parameters on a system-wide 
and individual VLAN interface basis. 
Enabling RIP 
RIP is disabled by default. To enable it, use one of the following methods. 
When you enable RIP, the default RIP version is RIPv2-only. You can change 
the RIP version on an individual interface basis to RIPv1 or 
RIPv1-compatible-v2 if needed. 
To enable RIP on a routing switch, enter the following commands: 
HPswitch(config)# ip routing 
HPswitch(config)# router rip 
HPswitch(rip)# exit 
HPswitch(config)# write memory
