iproute
Displays the current IP static routing configuration data. The meaning of each displayed field
for a route entry is:
D ESTINATION
IP address for the destination network or host.
S UBNET -M ASK
Subnet mask value for the destination network or host. A value of 255.255.255.255 indicates
that this entry is for a specific IP host.
N EXT H OP
IP address or device name for the next hop router that provides access to the destination
network or the host.
M ETRIC
Hop count to the destination network or the host.
iproute add
Allows an IP static route to be added to the current configuration. The required configuration
elements are explained below:
I S THIS THE DEFAULT ROUTE ?
Select whether or not this route is the default route or a route to a specific network that has been
previously configured. The default route is a form of a static route that is useful when there are
a large number of networks that can be accessed through a gateway. Care must be taken when
specifying a default route. All IP datagrams that specify a destination IP address that do not
have an explicit routing table entry will be sent to the default route. If this destination IP
address is unreachable, it could result in a large amount of unnecessary network traffic.
IP- ADDRESS
The Destination IP address using dotted decimal notation. 000.000.000.000 is used to specify the
default route coupled with Subnet-Mask value 000.000.000.000.
S UBNET -M ASK
The number of significant bits for the subnet mask using dotted decimal notation. The mask
bits start at the most significant bit of the IP address field and proceed to the least significant
bit. If this is a host specific route entry, the mask value must be 255.255.255.255. Use the default
if you are unsure of this value.
N EXT H OP
IP address using dotted decimal notation for the next hop router that provides access to the
network or the host specified by IP address. Next hop should be on the network directly
connected to a LAN interface or one of the CyberSWITCH IP sites. If next hop is one of the
system’s IP sites, the IP address for that site should be used.
M ETRIC V ALUE
Hop count to the destination network or the host.
