default_gateway
This command creates, shows, or deletes a pool of default gateways, with
nodes in the pool corresponding to different routes. Connections originating
from the system with a destination for which there is no other route choose a
route from the default gateway pool. Note that the default gateway pool is
not a last-hop pool for services running on the system.
There can be only one default gateway pool at any one time.
Defining a default gateway pool removes the need to define a default route.
However, if a default route is defined, that route will be used when all the
nodes in the default gateway pool are down.
Since the system performs route lookups on nodes as they are defined, the
default gateway pool must be stored at the top of the bigip.conf file. Also,
all nodes in the default gateway pool must reside on the same IP network as
the system.
We recommend that all nodes in the default gateway pool have the same
MTU.
As an alternative to using the default_gateway command, you can use the
Setup utility, which allows you to create the default gateway pool at the time
that you configure your base network.
