You can enter as many static IP addresses as necessary.
To view the configured routes, use the
show ip route static command (Figure 14-3).
Figure 14-3. show ip route static Command Example (partial)
FTOS installs a next hop that is on the directly connected subnet of the current IP address on the interface
(for example, if interface tengig 0/0 is on 172.31.5.0 subnet, FTOS installs the static route).
FTOS also installs a next hop that is not on the directly connected subnet but which recursively resolves to
a next hop on the interface's configured subnet. For example, if tengig 0/0 has ip address on subnet 2.2.2.0
and if 172.31.5.43 recursively resolves to 2.2.2.0, FTOS installs the static route.
• When an interface goes down, FTOS withdraws the route.
Command Syntax Command Mode Purpose
ip route ip-address mask {ip-address |
interface [ip-address]} [distance]
[permanent] [tag tag-value]
CONFIGURATION Configure a static IP address. Use the following
required and optional parameters:
• ip-address: Enter an address in dotted decimal
format (A.B.C.D).
•
mask: Enter a mask in slash prefix-length
format (/X).
• interface: Enter an interface type followed by
slot/port information.
•
distance range: 1 to 255 (optional).
• permanent: Keep the static route in the routing
table (if
interface option is used) even if the
interface with the route is disabled. (optional)
• tag tag-value range: 1 to 4294967295.
