I'm not sure about that Uchil. If the question says RIP not received on the
interface then surely that's most likely what you have to achieve. Perhaps
block the sending of updates upstream so the interface never recieves RIP
updates?

Hi,
Though the question says 'RIP routes neither sent or received on the
interface'.
Access-lists, Distribute-lists, Offset-lists will not prevent it being
received by the interface, as RIP updates are sent by other neighbors. So what
matters is what happens to the RIP update after it is received.
Best will be to use a Distribute-list to block all updates but Offset-lists
also can be used.

Requirement - 'RIP routes neither sent or received on the interface'
