this feature is enabled, RIP packets will be sent to the other routers on the
network telling them that data can still be sent to the WAN via this router.
Otherwise, the other routers will learn that the WAN link has been disconnected
and will no longer forward packets destined for the WAN to this router, causing
the packets to be dropped before Bandwidth on Demand has a chance to
reestablish the WAN connection.
IP Static Route
A static route is a permanent entry in the routing table. Static routing provides a
means of explicitly defining the next hop router for a particular destination network
IP address. Each static route entry also allows for a metric (a.k.a. hop count) to be
specified.
The parameters are described below:
•
IP Address – This specifies the destination network IP address (or a host,
depending on the netmask) and pairs it with a gateway.
•
Netmask – This mask shows how the destination IP address is to be divided into
network, subnet and host parts. The netmask has ones in the bit positions in the
32-bit address which are to be used for the network and subnet parts, and zeros
for the host part.
•
Gateway – This is the adjacent next hop router, for which the packets, arriving to
this router with this destination IP address, will be forwarded.
•
Hops – This is an associated RIP metric that may have its value set between 1
and 15, inclusive. A metric value higher than 15 (such as 16) means that the
network is unreachable.
