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 on the subnet associated with the default route, the invalid default route entry remains. You must manually delete the configured default route.
