establishment-criteria
   
      gre-config-instance
Configures the GRE tunnel establishment criteria
In a multi-controller RF domain, it is always the master node that establishes the tunnel. The tunnel is created only if the tunnel device is designated as one of the following: vrrp-master, cluster-master, or rf-domain-manager.
 
      Supported in the following platforms: 
         
         
            - Access Points — AP7502, AP7522,
               AP7532, AP7562, AP7602, AP7612, AP7622, AP7632, AP7662, AP8163, AP8432, AP8533
 
            - Wireless Controller — RFS4010
 
            - Service Platforms — NX5500, NX7500,
               NX9500, NX9600, VX9000

                     Configures the
                        GRE tunnel establishment criteria. The options are:
                           - always – Always
                              automatically establishes tunnel (default setting). The tunnel device
                              need not be a cluster master, RF Domain manager, or VRRP master to
                              establish the GRE tunnel. This is the default setting.
 
                           - cluster-master –
                              Establishes tunnel only if the tunnel device is designated as the
                              cluster master
 
                           - rf-domain-manager –
                              Establishes tunnel only if the tunnel device is designated as the RF
                              Domain manager
 
                           - vrrp-master <1-255>
                              – Establishes tunnel only if the tunnel device is designated as the
                              Virtual Router Redundancy (VRRP) master
                                 - <1-255> –
                                    Configures the VRRP group ID from 1 - 255. A VRRP group enables
                                    the creation of a group of routers as a default gateway for
                                    redundancy. Clients can point to the IP address of the VRRP
                                    virtual router as their default gateway and utilize a different
                                    group member if a master becomes unavailable.
