Examples of Displaying IPv6 RDNSS Information

The following example displays IPv6 RDNSS information. The output in the last 3 lines indicates that the IPv6 RDNSS was correctly configured on interface te 1/1.

DellEMC#show ipv6 interface te 1/1

To display IPv6 RDNSS information, use the show configuration command in INTERFACE CONFIG mode.

DellEMC(conf-if-te-1/1)#show configuration 

The following example uses the show configuration command to display IPv6 RDNSS information.
