Switch Feature Overview 91
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 "VRRP " on page 1295.
Tunnel and Loopback Interfaces
Dell Networking N-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 a stable IP address can be configured to enable
other network devices to contact or identify the switch.
For information about configuring tunnel and loopback interfaces, see
"Routing Interfaces " on page 1141.
