(Optional) Configuring a Gateway Address for Clients

Context

If a gateway address for clients is configured on the DHCP server, clients obtain the gateway address from the DHCP server and automatically generate a default route to the gateway address. Then the clients can access the hosts on other network segments. If the DHCP server is configured with Option 121 to allocate classless static routes to clients, the clients generate routes based on only the static routes and does not generate a default route to the gateway address. To load balance traffic and improve network reliability, configure multiple gateway addresses. A maximum of eight gateway addresses can be configured for each address pool.

In the scenario where both VRRP and DHCP are configured, if a VRRP group functions as the DHCP server, configure the gateway address of clients as the virtual IP address of the VRRP group.

If the DHCP server and clients are on the same network segment and the DHCP server functions as the gateway of clients, you do not need to configure a gateway address for clients.

Procedure

Configure a gateway address in the interface address pool view.
1. Enter the system view.
```
system-view 
```
2. Enter the interface view.
```
interface interface-type interface-number
```
3. Specify a gateway address that the DHCP server sends to clients.
```
dhcp server gateway-list ip-address &<1-8>
```
  By default, no gateway address is configured.
Configure a gateway address in the global address pool view.
1. Enter the system view.
```
system-view
```
2. Enter the global address pool view.
```
ip pool ip-pool-name
```
3. Specify a gateway address that the DHCP server sends to clients.
```
gateway-list ip-address &<1-8>
```
  By default, no egress gateway address is configured.
