NetStructure™ 480T Routing Switch User Guide
The following commands are used to configure both VLAN Sales
switches. The assumption is that the inter-router backbone is
running OSPF, with other routed VLANs already properly
configured. Similar commands would be used to configure a switch
on a network running RIP. The primary requirement is that the IP
address for the VLAN(s) running ESRP must be identical. In this
scenario, the master is determined by the programmed MAC
address of the switch, because the number of active links for the
VLAN and the priority are identical to both switches.
These are the commands used to configure the VLAN Sales
switches:
create vlan sales
configure sales add port 1-4
configure sales ipaddr 10.1.2.3/24
enable ipforwarding
enable esrp sales
enable edp ports all
configure ospf add vlan sales
enable ospf
