talk-listen
talk-only

ip rip poison-reverse

User level: read-write, admin.
You can only access this command in interface mode.
Type interface [name] at the command prompt to enter interface mode if
necessary.
Use the ip rip poison-reverse command to enable split-horizon with
poison-reverse on an interface.
Use the no ip poison-reverse command to disable the poison-reverse
mechanism.
The split-horizon technique prevents information about routes from exiting the
router interface through which the information was received. This prevents routing
loops.
Poison reverse updates explicitly indicate that a network or subnet is unreachable
rather than implying they are not reachable. Poison reverse updates are sent to
defeat large routing loops.
