Using GRE Tunnel for HSRP redundancy over layer 3 network

Hi, 

 

DC1- Controller    ------------- L3 network --------------- DC2 Controller

( Master-Master)                                                           ( Master- Backup)

 -------------------------------- VRRP over GRE--------------------------------

        |                                                                                      |

     GRE                                                                                GRE

        |                                                                                      |

 

Site 1- Controller                                                           Site 2 - Controller

 

Guest Vlan x                                                                   Guest Vlan x 

 

Need help with setting up the above topology whereby we have two sites controllers and two Master/Backup controller separated by layer 3 network. The requirement is to tunnel (GRE) Guest VLAN from site 1 and 2 to  active Master controller at DC1 and automatically failover to Master -Backup controller at DC2 in the event DC1 controller goes down. Is this possible. Help , highly appreciated. Thanks

For tunnel redundancy, you should look into the tunnel groups feature:  http://www.arubanetworks.com/techdocs/ArubaOS_63_Web_Help/Web_Help_Index.htm#ArubaFrameStyles/Network_Parameters/Configuring_GRE_Tunnel_Group.htm

Many thanks CJoseph. Is tunnel group feature supported on 6.2 ?

 

If not , what other option do I have ?

There is no other real option, that is why it was introduced in 6.3
