The IP RIP propagation control determines how a static route is propagated via IP RIP. The
following table provides an explanation of how a IP RIP propagation control flag is assigned to
a static route.

Allows an existing IP static route to be changed.

The Subnet mask for the destination (sub-) network. A subnet mask of 255.255.255.255 implies that
this static route entry is for a host rather than a (sub-) network. The Subnet mask is specified by
entering the number of contiguous bits that are set for the mask. The mask bits start at the most
significant bit of the IP address field and proceed to the least significant bit.

configuration element is the device name) for the next hop gateway that provides access to the
target (sub-) network or host. The IP address (or the device name) of the Next Hop must be on the
(sub) network connected to a defined interface.

The administrative distance to the destination of the entry. The administrative distance is typically
measured by the number of hop counts (number of routers) between the CyberSWITCH and the
destination, but it is up to you to assign proper value to each route entry. If multiple routes exist to
the same destination, the route with the least metric value will be chosen as its primary route. Care
must be taken when assigning the metric value of 0, because it is interpreted that the destination is
measured by the number of hop counts (number of routers) between the CyberSWITCH and the
destination, but it is up to you to assign proper value to each route entry. If multiple routes exist to
the same destination, the route with the least metric value will be chosen as its primary route. Care

Flag
Meaning
Propagate Always
This flag indicates that the route information is always
propagated via IP RIP.
This flag is available when the next hop is over a LAN
or a WAN interface.
propagated via IP RIP.
This flag is available when the next hop is over a LAN
or a WAN interface.
Propagate only
when the Next
Hop is Connected
when the Next
Hop is Connected
This flag indicates that the route information is
propagated via IP RIP only when the next hop router is
connected to the system.
This flag is available when the next hop is over a LAN
or a WAN interface.
propagated via IP RIP only when the next hop router is
connected to the system.
This flag is available when the next hop is over a LAN
or a WAN interface.
Do Not Propagate
This flag indicates that the static route information is not
propagated over the interface.
This flag is available only when the next hop is over a
WAN interface.
propagated over the interface.
This flag is available only when the next hop is over a
WAN interface.
