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.
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.
