The configuration of Basic VRRP In MSR Series

The configuration of Basic VRRP In MSR Series

 

 

Keywords: MSR;VRRP

I            Requirement for the diagram

Router RTA and RTB consist of VRRP to provide redundancy.  In this way, PC1 and PC2 can reach RTC when one of RTA or RTB fault.

Device List: 3 MSR; 1 Switch; 2 PC;

CMW Version: Version 5.20, Beta 1106

II          Network topology

Figure 1 MSR VRRP

III        Steps of configuration

 Config the address of PC1: 172.10.1.6/16, Gateway:172.10.2.1

RTA

＃ interface Ethernet 0/0  ip address 172.10.1.1 255.255.0.0  vrrp vrid 1 virtual-ip 172.10.2.1  vrrp vrid 1 priority 150 # interface Ethernet0/1  port link-mode route  ip address 192.168.1.1 255.255.255.0 ＃ rip  network 172.10.0.0  network 192.168.1.0

RTB

# interface Ethernet0/0 ip address 172.10.1.2 255.255.0.0 vrrp vrid 1 virtual-ip 172.10.2.1 # interface Ethernet0/1 ip address 192.168.2.1 255.255.255.0 # rip network 172.10.0.0  network 192.168.2.0

RTC

# interface Ethernet0/0 ip address 192.168.1.2 255.255.255.0 # interface Ethernet0/1 ip address 192.168.2.2 255.255.255.0 # interface LoopBack1 ip address 192.168.8.8 255.255.255.255 # rip network 192.168.1.0 network 192.168.2.0 network 192.168.8.0

 

IV       Result Check

1) display vrrp state of RTA:

       [RTA]dis vrrp

 IPv4 Standby Information:

 Run Method     : VIRTUAL-MAC 

 Virtual Ip Ping : Enable

                Interface      : Ethernet0/0            

                VRID           : 1                   Adver. Timer   : 1                  

 Admin Status   : UP                  State          : Master             

 Config Pri     : 150                 Run Pri        : 150     

 Preempt Mode   : YES                 Delay Time     : 0        

 Auth Type      : NONE              

                  Virtual IP     : 172.10.2.1        

                  Virtual MAC    : 0000-5e00-0101    

                  Master IP      : 172.10.1.1

2) On pc1, pint the loopback address of RTC as blow:

C:\>ping–t 192.168.8.8 can receive reply

Shutdown the interface of Ethernet0/0 of RTA，we can see there has one package lost, and the state of vrrp is：

<RTA>dis vrrp

 IPv4 Standby Information:

 Run Method     : VIRTUAL-MAC 

 Virtual Ip Ping : Enable

 Interface      : Ethernet0/0            

 VRID           : 1                   Adver. Timer   : 1                  

 Admin Status   : UP                  State          : Initialize         

 Config Pri     : 150                 Run Pri        : 150     

 Preempt Mode   : YES                 Delay Time     : 0        

 Auth Type      : NONE              

 Virtual IP     : 172.10.2.1        

 Master IP      : 0.0.0.0

Now, the vrrp state of RTB：

         [RTB]dis vrrp

 IPv4 Standby Information:

 Run Method     : VIRTUAL-MAC

 Virtual Ip Ping : Enable

 Interface      : Ethernet0/0

 VRID           : 1                   Adver. Timer   : 1

 Admin Status   : UP                  State          : Master

 Config Pri     : 100                 Run Pri        : 100

 Preempt Mode   : YES                 Delay Time     : 0

 Auth Type      : NONE

 Virtual IP     : 172.10.2.1

 Master IP      : 172.10.1.1
