If you specify this information in the IPv6 RDNSS configuration, a DNS error is displayed.
Example for Configuring an IPv6 Recursive DNS Server
The following example configures a RDNNS server with an IPv6 address of 1000::1 and a lifetime of 1
second.
Debugging IPv6 RDNSS Information Sent to the Host
To verify that the IPv6 RDNSS information sent to the host is configured correctly, use the debug ipv6
nd command in EXEC Privilege mode.
Example of Debugging IPv6 RDNSS Information Sent to the Host
The following example debugs IPv6 RDNSS information sent to the host.
The last 3 lines indicate that the IPv6 RDNSS information was configured correctly.
dns-server=1000::0001, lifetime=1 sec
dns-server=3000::0001, lifetime=1 sec
dns-server=2000::0001, lifetime=0 sec
If the DNS server information is not displayed, verify that the IPv6 recursive DNS server configuration was
configured on the correct interface.
Displaying IPv6 RDNSS Information
To display IPv6 interface information, including IPv6 RDNSS information, use the show ipv6
interface
command in EXEC or EXEC Privilege mode.
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.
To display IPv6 RDNSS information, use the show configuration command in INTERFACE CONFIG
mode.
The following example uses the show configuration command to display IPv6 RDNSS information.
IPv6 Multicast
IPv6 multicast is supported on the MXL switch platform.
The Dell Networking OS supports the following protocols to implement IPv6 multicast routing:
• Multicast listener discovery protocol (MLD) — MLD on a multicast router sends out periodic general
MLD queries that the switch forwards through all ports in the VLAN. There are two versions of MLD:
MLD version 1 is based on version 2 of the Internet group management protocol (IGMP) for IPv4; MLD
version 2 is based on version 3 of the IGMP for IPv4. IPv6 multicast for the Dell Networking OS
supports versions 1 and 2.
• Protocol-independent multicast-sparse mode (PIM-SM) — PIM-SM is a multicast protocol in which
multicast receivers explicitly join to receive multicast traffic. The protocol uses a router as the root or
