Configuration examples with Layer 3 routing support
2
DRAFT: BROCADE CONFIDENTIAL
The following commands add the paths through the firewalls to the other ServerIron ADX. Each
path consists of a path number, a ServerIron ADX port number, the IP address at the other end of
the path, and the next-hop IP address. In this example, the topology does not contain routers other
than the ServerIron ADXs. If your topology contains other routers, configure firewall paths for the
routers too. For router paths, use the same IP address as the path destination and the next hop.
NOTE
The path IDs must be in contiguous, ascending numerical order, starting with 1. For example, path
sequence 1, 2, 3, 4 is valid. Path sequence 4, 3, 2, 1 or 1, 3, 4, 5 is not valid.
SI-External(config-fw-2)# fwall-info 1 4/1 10.10.2.222 10.10.1.5
SI-External(config-fw-2)# fwall-info 2 4/2 10.10.2.222 10.10.1.6
The following command sets the load balancing method to balance requests based on the firewall
that has the least number of connections for the requested service.
SI-External(config-fw-2)# fw-predictor per-service-least-conn
SI-External(config-fw-2)# exit
The following command saves the configuration changes to the startup-config file.
SI-External(config)# write memory
