+VRRP daemon (vrrpd) is an RFC 2338 compliant implementation of the 
+Virtual Router Redundancy Protocol (VRRP). The Virtual Router Redundancy
+Protocol is designed to eliminate the single point of failure associated
+with statically routed networks by automatically providing failover using
+multiple LAN paths through alternate routers.
+
+As specified in RFC 2338, VRRP uses an election protocol that dynamically
+assigns responsibility for a virtual router to one of the VRRP routers on
+a LAN. When a VRRP router controls the IP address(es) associated with a
+virtual router, it is called the Master. The Master continues to forward
+packets sent to these IP addresses until it has a problem that causes the
+VRRP routers to hold an election. The election process provides dynamic
+failover by electing a new Master should the existing Master become
+unavailable.
+
+The virtual router associated with each alternate path under VRRP uses the
+same IP address and MAC address as the routers for other paths. As a result,
+the host's gateway information does not change, no matter what path is used.
+Because of this design, VRRP-based redundancy significantly reduces
+administrative overhead when compared to redundancy schemes that require
+hosts to be configured with multiple default gateways.
+
+The primary function of the Virtual Router Redundancy Protocol is to provide
+routing redundancy for specific IP addresses. In addition to this primary
+function, RFC 2338 also states that the protocol should:
+
+ * Minimize the duration of black holes.
+ * Minimize the steady state bandwidth overhead and processing complexity.
+ * Function over a variety of multiaccess LAN technologies that support IP
+    traffic.
+ * Provide for election of multiple virtual routers on a network for load
+    balancing.
+ * Support multiple logical IP subnets on a single LAN segment.

+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also

+vrrpd: vrrpd (Virtual Router Redundancy Protocol)
+vrrpd:
+vrrpd: VRRPd is an implementation of Virtual Router Redundancy Protocol
+vrrpd: as specified in rfc2338. VRRPd is interoperable with other RFC-based
+vrrpd: VRRP implementations, including Cisco and Juniper, and is included
+vrrpd: as a standard feature on ImageStream routers.
