(VRRP)
The Virtual Routing Redundancy Protocol (VRRP) can prevent a loss of
network operations for end hosts due to the failure of the static default IP
gateway. VRRP accomplishes this by allowing you to designate a number
of other routers as Backup routers in the event that the Master router (the
default router) should fail for any reason.
Topics covered in this chapter include:
■
VRRP Overview
■
Key Concepts
■
Important Considerations
■
VRRP and Other Networking Operations
■
Using VRRP On Your Switch 4007
■
Configuring VRRP
■
Standards, Protocols, and Related Reading
Before you implement VRRP, be sure that you have a good understanding
of how IP networks function. See Chapter 16 for more information about
IP networks. Also, be sure to read this chapter thoroughly before you set
up VRRP on your network.
After you log in to the system and connect to a slot that houses a
Multilayer Switching Module, you can manage VRRP in these ways:
■
From the
vrrp
menu of the Administration Console. (See the Switch
4007 Command Reference Guide. )
■
From the VRRP folder of the Web Management software. (See the
Switch 4007 Getting Started Guide .)
The management interfaces display “
cb9000
” and refer to the
Management Module as the Enterprise Management Engine (EME)
because the heritage of the Switch 4007 is the CoreBuilder
