Hello there,

i have two aruba controllers 7210 verion 8.3.0.6 need to apply vrrp on them, can any one share with me what is the configuration and the steps in sequence, also wanted to know what is the role of each controller while configuring them for the first time (master-standalone-md)

Thanks in advance

Have you seen the article here?  https://www.arubanetworks.com/techdocs/ArubaOS_83_Web_Help/content/arubaframestyles/vrrp/vrrp_redund.htm?Highlight=vrrp

thanks you sir so much for such a document, but i have one question, now one i start to make one controller (MD) role, it asks for a mobility master and second mobility master IP, while i am not configuring a mobility master in my network, i just want to have two controllers (7210) to work in a vrrp an HA for redundancy, so do you have any recomendations ?

thanks

You configure the VRRP on each md without the master redundancy part.

once i set one controller to act as (MD) i couldnt apply any configuration on it neither GUI nor CLI, on the gui it says "this is a managed device it must be configured from its master."

Do you have an MM in your network?

No sir

Your controller should be configured as "Standalone".  MD stands for "managed device", which means that an MM is managing it.  That is not what you want.  Do a "write erase all" to provision it as a Standalone, instead.

In the CLi

Execute the following CLI commands on both Mobility Masters:

(MM-Primary) [mynode] (config) #vrrp <id>

(MM-Primary) ^[mynode] (config-submode)#ip address <ip addr>

(MM-Primary) ^[mynode] (config-submode)#vlan <id>

(MM-Primary) ^[mynode] (config-submode)#description <string>

(MM-Primary) ^[mynode] (config-submode)#priority <level>

(MM-Primary) ^[mynode] (config-submode)#no shutdown

The following sample CLI commands configure virtual router 10 on the initially-preferred master:

(MM-Primary) [mynode] (config) #vrrp 10

(MM-Primary) ^[mynode] (config-submode)#ip address 192.168.10.245

(MM-Primary) ^[mynode] (config-submode)#vlan 1

(MM-Primary) ^[mynode] (config-submode)#description "Preferred-Master"

(MM-Primary) ^[mynode] (config-submode)#priority 200

(MM-Primary) ^[mynode] (config-submode)#no shutdown

The following sample is the corresponding VRRP configuration for the backup Mobility Master:

(MM-Backup) [mynode] (config) #vrrp 10

(MM-Backup) ^[mynode] (config-submode)#ip address 192.168.10.245

(MM-Backup) ^[mynode] (config-submode)#vlan 1

(MM-Backup) ^[mynode] (config-submode)#description "Backup-Master"

(MM-Backup) ^[mynode] (config-submode)#priority 100

(MM-Backup) ^[mynode] (config-submode)#no shutdown

Verifying VRRP Configuration

Execute the following CLI command on the Mobility Master (both primary and backup) to verify the VRRP configuration:

(MM-Primary) [mynode] #show vrrp <id>

The following output is displayed on the primary Mobility Master:

(MM-Primary) [mynode] #show vrrp 10

Virtual Router 10:

Description

Admin State UP, VR State MASTER

IP Address 192.168.10.245, MAC Address 00:00:5e:00:01:34, vlan 1

Priority 200, Advertisement 1 sec, Preemption Disable Delay 0

Auth type NONE ********

tracking is not enabled

The following output is displayed on the backup Mobility Master:

(MM-Backup) [mynode] #show vrrp 10

Virtual Router 10:

Description

Admin State UP, VR State BACKUP

IP Address 192.168.10.245, MAC Address 00:00:5e:00:01:34, vlan 1

Priority 100, Advertisement 1 sec, Preemption Disable Delay 0

Auth type NONE ********

tracking is not enabled

The following sample commands configure Master redundancy on the primary Mobility Master:

(MM-Primary) [mynode] (config) #master-redundancy

(MM-Primary) [mynode] (config-submode)#master-vrrp 10

(MM-Primary) ^[mynode] (config-submode)#peer-ip-address 192.168.10.244 ipsec aruba123

(MM-Primary) ^[mynode] (config) #write memory

The following sample is a Master redundancy configuration on the backup Mobility Master:

(MM-Backup) [mynode] (config) #master-redundancy

(MM-Backup) [mynode] (config-submode)#master-vrrp 10

(MM-Backup) ^[mynode] (config-submode)#peer-ip-address 192.168.10.243 ipsec aruba123

(MM-Backup) ^[mynode] (config) #write memory
