VRRP
Virtual Router Redundancy Protocol (VRRP) combines a group of
switches (including a master and multiple backups) on a LAN into a virtual
router called VRRP group. VRRP streamlines host configuration while
providing high reliability. This document describes:

RRPP
RRPP is a link layer protocol designed for Ethernet rings. RRPP can
prevent broadcast storms caused by data loops when an Ethernet ring is
healthy, and rapidly restore the communication paths between the nodes
after a link is disconnected on the ring. This document describes:
