Changing The Route Loop Prevention Method; Viewing Rip Information; Viewing General Rip Information - HP 2920 Series Multicast And Routing Manual

The no form of the command disables redistribution for the specified route type.
Example:
To enable redistribution of all connected, static, and OSPF routes into RIP, enter the following
commands.
HP Switch(config)# router rip
HP Switch(rip)# redistribute connected
HP Switch(rip)# redistribute static
HP Switch(rip)# write memory

Changing the route loop prevention method

Syntax:
[no] ip rip poison-reverse
Entering the command without the no option will re-enable Poison reverse.
RIP can use the following methods to prevent routing loops:
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 ("infinity" or "unreachable") to a route
before advertising it on the same interface as the one on which the routing switch learned the
route. This is the default.
These loop prevention methods are configurable on an individual VLAN interface basis.
NOTE: These methods are in addition to RIP's maximum valid route cost of 15.
Poison reverse is enabled by default. Disabling Poison reverse causes the routing switch to revert
to Split horizon. (Poison reverse is an extension of Split horizon.) To disable Poison reverse on an
interface, and thereby enable Split horizon, enter the following:
HP Switch(config)# vlan 1
HP Switch(vlan-1)# no ip rip poison-reverse

Viewing RIP information

All RIP configuration and status information is shown by the CLI command show ip rip and
options off that command.

Viewing general RIP information

Syntax:
show ip rip
To display general RIP information, enter show ip rip at any context level. The resulting display
will appear similar to the following:
