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 on the following devices:

Syntax

establishment-criteria [always|cluster-master|rf-domain-manager|vrrp-master <1-255>]

Parameters

establishment-criteria [always|cluster-master|rf-domain-manager|vrrp-master <1-255>]
establishment-criteria [always| cluster-master| rf-domain-manager| vrrp-master <1-255>] 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.
