This read-write Integer32 (1-255, default 120) sets the administrative distance assigned to routes learned via RIP; lower distances are preferred over higher ones when multiple protocols offer the same route. Admins adjust it to make RIP routes more or less trusted relative to routes from other protocols like OSPF running on the same switch. For example, lowering this to 90 would make RIP-learned routes preferred over a competing protocol whose distance remains at 110.
