Syntax
Parameter Description Default
mode {l2|l3}
Set the type of tunnel-group. l3
no
Negates any parameter configured. —
preemptive-failover
When enabled, this option automatically redirects the
traffic upon detecting an active tunnel with a higher
precedence in the tunnel-group. When disabled, the traffic
gets redirected to a higher precedence tunnel only when
the tunnel carrying the traffic fails.
enabled
tunnel <tunnel-id>
Adds the specified tunnel ID to the tunnel group. The
range is 1-16777215.

Usage Guidelines
Use this command to provide redundancy for L3 generic routing encapsulation (GRE) tunnels. This feature
enables automatic redirection of the user traffic to a standby tunnel when the primary tunnel goes down.
To enable L3 GRE tunnel group, you must:
l configure a tunnel-group to group a set of tunnels.
l enable tunnel keepalives on all the tunnel interfaces assigned to the tunnel-group, and
l configure the session ACL with the tunnel-group as the redirect destination.
To enable L2 GRE tunnel group, you must:
l configure the member tunnel and add them to the appropriate VLAN.
l enable tunnel keepalives on the tunnel interface.
l configure the tunnel-group and set the group type to L2, and
l add the member tunnel to the group
You can configure up to 32 tunnel-groups on a controller with a maximum of 5 tunnels in each tunnel-group.
Example
The following set of commands create a tunnel-group with tunnel IDs 10 and 20 as the members:
