The configuration of Load-balance with VRRP In MSR

The configuration of Load-balance with VRRP In MSR

 

 

Keywords: MSR;VRRP;Load-balance

I            Requirement for the diagram

Two routers RTA and RTB join two VRRP group, for redundancy and load-balancing.

Device List: 3, MSR; 2, Switch; 2 PC

CMW Version: Version 5.20, Beta 110

II          Network topology

 Figure1-1 MSR vrrp

IP address notes：

(As show above：The address between RTA and RTC is 192.168.1.0/24，RTC and RTB is 192.168.2.0/24)

    RTA： E0/0: 172.10.1.1/16     E0/1: 192.168.1.1/24

    RTB： E0/0: 172.10.1.2/16     E0/1: 192.168.2.1/24

    RTC： E0/0: 192.168.1.2/24    E0/1: 192.168.2.2/24

Vrrp interface 1: 172.10.2.1

 Vrrp interface 2: 172.10.3.1

III        Steps of configuration

IV       Key notes in the configuration

1) After configuration, Tracert Loopback1 of RTC from PC1, data passing RTA and reach RTC. Tracert Loopback1 of RTC from PC2, data passing RTB and reach RTC.

2) After shutdown G0/0 of RTA, checking vrrp info of RTB, has result below:

after shut down RTA gi 0/0:

As we can see，two virtual gateway of vrrp all in RTB.
