◆
The default gateway can also be defined using the following command:
ip route 0.0.0.0 0.0.0.0 gateway-address .
◆
Static routes can also be defined using the ip route command to ensure
that traffic to the designated address or subnet passes through a
preferred gateway.
◆
A default gateway can only be successfully set when a network
interface that directly connects to the gateway has been configured on
the router.
◆
The same link-local address may be used by different interfaces/nodes
in different zones (RFC 4007). Therefore, when specifying a link-local
address for a default gateway, include zone-id information indicating
the VLAN identifier after the % delimiter. For example, FE80::7272%1
identifies VLAN 1 as the interface from which the ping is sent.
