Parameter Description
Authentication Type Authentication can be used to ensure that routing information comes from a valid
source.
Authentication Key A simple password must be provided if authentication is enabled. (An
authentication string is case sensitive, and can be up to 16 characters.)
Send Type The protocol used for traffic sent out this port:
RIP1 Broadcast— Route information is broadcast to other routers on the network
using RIPv1.
RIP2 Broadcast— Route information is broadcast to other routers on the network
using RIPv2.
RIP2 Multicast— Route information is multicast to other routers on the network
using RIPv2.
Do Not Send— The switch will passively monitor route information advertised by
other routers attached to the network.
Receive Type The routing protocol messages accepted on this port includes RIP1, RIP2,
RIP1/RIP2, or Disabled (i.e., none received).
Default Metric A “metric” indicates the number of hops between the switch and the destination
network.
The “default metric” is used for the default route in RIP updates originated on this
interface. A value of zero indicates that no default route should be originated; in this
case, a default route via another router may be propagated.
Range: 0-15
Poison Reverse* Propagates routes back to an interface port from which they have been acquired,
but sets the distance vector metrics to infinity.
NOTE: This is a method of preventing routing information from looping back to the source. Note that
Split Horizon is also enabled on this switch for this purpose. (See “6.2.6.1 RIP and RIP-2
Dynamic Routing Protocols”.)
