A default route or gateway defines a default interface to which traffic is directed when no specific routes are available. To add a default route, use the command:
configure iproute add default gateway {metric} {multicast | multicast-only | unicast | unicast-only} {vr vrname}
Note
If you define a default route and subsequently delete the VLAN (Virtual LAN) on the subnet associated with the default route, the invalid default route entry remains. You must manually delete the configured default route.
