gateway-list
Function
The gateway-list command configures the egress gateway address for the DHCP client.
The undo gateway-list command deletes a configured egress gateway address.
By default, no egress gateway address is configured.
Usage Guidelines
Usage Scenario
This command applies to DHCP servers. If a DHCP server and its client are on different network segments, you can run the gateway-list command to specify an egress gateway address. In this way, the DHCP server and client can communicate with each other. Then the DHCP server can assign both an IP address and the specified egress gateway address to the client. You can configure multiple gateways in a global address pool to load balance traffic and improve network reliability.
Run the gateway (DHCP server group view) command to configure an egress gateway for a DHCP relay agent.
Configuration Impact
If a gateway address is configured on the DHCP server, a DHCP client obtains the gateway address from the DHCP server and automatically generates a default route to the gateway address. If you run the option121 command on the DHCP server to allocate classless static routes to DHCP clients, the DHCP client uses an allocated classless static route and does not automatically generate a default route to the gateway address.
Precautions
In the IP address pool view and DHCP Option template view, the AC can be configured with a maximum of eight egress gateway addresses respectively. These gateway addresses cannot be subnet broadcast addresses.
When configuring an egress gateway address for the global address pool of a DHCP server, ensure that this egress gateway address is the same as that of the DHCP relay agent.
Example
# In the IP address pool view, set the egress gateway address for the DHCP client to 10.1.1.1.
<AC6605> system-view [AC6605] ip pool global1 [AC6605-ip-pool-global1] gateway-list 10.1.1.1
<AC6605> system-view [AC6605] dhcp option template template1 [AC6605-dhcp-option-template-template1] gateway-list 10.1.1.1
