This chapter describes how to configure Layer 3 Switches with the following router redundancy
protocols:
• Virtual Router Redundancy Protocol (VRRP) – The standard router redundancy protocol
described in RFC 2338.
• VRRP Extended (VRRPE) – An enhanced version of VRRP that overcomes limitations in the
standard protocol.
NOTE
VRRP and VRRPE are separate protocols. You cannot use them together.
NOTE
You can use a Layer 3 Switch configured for VRRP with another Layer 3 Switch or a third-party router
that is also configured for VRRP. However, you can use a Layer 3 Switch configured for VRRPE only
with another Layer 3 Switch that also is configured for VRRPE.
For a summary of how these two router redundancy protocols differ, refer to “Comparison of VRRP
and VRRPE” on page 871.
Overview
The following sections describe VRRP and VRRPE. The protocols both provide redundant paths for
IP addresses. However, the protocols differ in a few important ways. For clarity, each protocol is
described separately.
