Virtual Router Redundancy Protocol (VRRP)

VRRP provides hosts with redundant routers in the network topology without
any need for the hosts to reconfigure or know that there are multiple routers.
If the primary (master) router fails, a secondary router assumes control and
continues to use the virtual router IP (VRIP) address.
VRRP Route Interface Tracking extends the capability of VRRP to allow
tracking of specific route/interface IP states within the router that can alter
the priority level of a virtual router for a VRRP group.
For information about configuring VRRP settings, see "Configuring VRRP"
on page 1035.

Tunnel and Loopback Interfaces

PowerConnect 8000-series and 8100-series switches support the creation,
deletion, and management of tunnel and loopback interfaces. Tunnel
interfaces facilitate the transition of IPv4 networks to IPv6 networks. A
loopback interface is always expected to be up, so you can configure a stable
IP address that other network devices use to contact or identify the switch.
For information about configuring tunnel and loopback interfaces, see
"Configuring Routing Interfaces" on page 843.

IPv6 Routing Features

IPv6 Configuration

The switch supports IPv6, the next generation of the Internet Protocol. You
can globally enable IPv6 on the switch and configure settings such as the IPv6
hop limit and ICMPv6 rate limit error interval. You can also control whether
IPv6 is enabled on a specific interface. The switch supports the configuration
of many per-interface IPv6 settings including the IPv6 prefix and prefix
length.
For information about configuring general IPv6 routing settings, see
"Configuring IPv6 Routing" on page 1059.
