USER’S GUIDE

IP RIP PROPAGATION CONTROL

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.

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.
Propagate only	This flag indicates that the route information is
when the Next	propagated via IP RIP only when the next hop router is
Hop is Connected	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.

iproute change

Allows an existing IP static route to be changed.

iproute delete

Allows an IP static route to be deleted from the current configuration.

STATIC ROUTE CONFIGURATION ELEMENTS

DESTINATION IP ADDRESS

IP address using dotted decimal notation that specifies the destination (sub-) network or host.

SUBNET MASK

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.

NEXT HOP ADDRESS

IP address using dotted decimal notation (or if an unnumbered WAN interface is used, this 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.

METRIC VALUE

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
