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 1033.

PowerConnect M6220, M6348, M8024, and M8024-k 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 855.

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

For information about configuring general IPv6 routing settings, see

"Configuring IPv6 Routing" on page 1057.
