Router (config − Ethernet0.1) # exit Enter
Router (config) # proxy − dns server (DNS − server − address) Enter
Router (config) # proxy − dns enable Enter
Router (config) #
MEMO: If using proxy DNS, register the IP address set in the FastEthernet0.0 of the
To let IPCP automatically acquire the address of the DNS server, perform the following instead of the above example.
Router (config − Ethernet0.1) # exit Enter
Router (config) # proxy − dns dynamic ipcp Enter
Router (config) # proxy − dns enable Enter
Router (config) #
Shutting down a PPPoE connection
To shut down a PPPoE connection, be sure to use the shutdown command. This causes a PPPoE discon- nection sequence to be performed between the
Router (config) # interface FastEthernet0.0 Enter
Router (config − FastEthernet0.0) # shutdown Enter
Router (config − FastEthernet0.0) #
NOTE: If you shut down a connection by turning OFF the power switch or by other means, instead of using the shutdown command, it will take a few minutes to establish the next connection.
