BLADEOS 6.5.2 Application Guide

BLADEOS Extensions to VRRP

This section describes VRRP enhancements that are implemented in BLADEOS.

BLADEOS supports a tracking function that dynamically modifies the priority of a VRRP router, based on its current state. The objective of tracking is to have, whenever possible, the master bidding processes for various virtual routers in a LAN converge on the same switch. Tracking ensures that the selected switch is the one that offers optimal network performance. For tracking to have any effect on virtual router operation, preemption must be enabled.

BLADEOS can track the attributes listed in Table 23 (Router VRRP mode):

Parameter

Description

 

 

Number of IP interfaces on the switch

Helps elect the virtual routers with the most available

that are active (“up”)

routes as the master. (An IP interface is considered

tracking-priority-increment

active when there is at least one active port on the same

VLAN.) This parameter influences the VRRP router's

interfaces

priority in virtual interface routers.

Number of virtual routers in master mode

Useful for ensuring that traffic for any particular

on the switch

client/server pair is handled by the same switch,

tracking-priority-increment

increasing routing efficiency. This parameter

influences the VRRP router's priority in virtual

virtual-routers

interface routers.

 

 

 

Each tracked parameter has a user-configurable weight associated with it. As the count associated with each tracked item increases (or decreases), so does the VRRP router's priority, subject to the weighting associated with each tracked item. If the priority level of a standby is greater than that of the current master, then the standby can assume the role of the master.

See “Configuring the Switch for Tracking” on page 337 for an example on how to configure the switch for tracking VRRP priority.
