Before adding a route, if the IP addresses in the route pertain to any route
domains, verify that the relevant route domains are present on the system.
Perform this task when you want to explicitly add a route for a destination that is
not on the directly-connected network. Depending on the settings you choose, the
BIG-IP system can forward packets to a specified network device (such as a next-hop
router or a destination server), or the system can drop packets altogether.
-
On the Main tab, click .
-
Click Add.
The New Route screen opens.
-
In the Name field, type a unique user name.
This name can be any combination of alphanumeric characters, including an IP
address.
-
Optional:
In the Description field, type a
description for this route entry.
-
In the Destination field, type either the destination IP
address for the route, or IP address 0.0.0.0 for the
default route.
This address can represent either a host or a network. Also, if you are using
the route domains and the relevant route domain is the partition default route
domain, you do not need to append a route domain ID to this address.
-
In the Netmask field, type the network mask for the
destination IP address.
-
From the Resource list, specify the method through which
the system forwards packets:
Option |
Description |
Use Gateway
|
Select this option when you want the next hop in the route to be a
network IP address. This choice works well when the destination is a
pool member on the same internal network as this gateway
address. |
Use Pool
|
Select this option when you want the next hop in the route to be a
pool of routers instead of a single next-hop router. If you select this
option, verify that you have created a pool on the BIG-IP system, with
the routers as pool members. |
Use VLAN/Tunnel
|
Select this option when you want the next hop in the route to be a
VLAN or tunnel. This option works well when the destination address you
specify in the routing entry is a network address. Selecting a
VLAN/tunnel name as the resource implies that the specified network is
directly connected to the BIG-IP system. In this case, the BIG-IP system
can find the destination host simply by sending an ARP request to the
hosts in the specified VLAN, thereby obtaining the destination host’s
MAC address. |
Reject
|
Select this option when you want the BIG-IP system to reject packets
sent to the specified destination. |
-
In the MTU field, specify in bytes a maximum
transmission unit (MTU) for this route.
-
Click Finished.
After you perform this task, a static route is defined on the BIG-IP system with IP
addresses that can pertain to one or more route domains.
You should define a default route for each route domain on the system. Otherwise,
certain types of administrative traffic that would normally use a TMM interface
might instead use the management interface.
