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 GREGeneric Routing Encapsulation. GRE is an IP encapsulation protocol that is used to transport packets over a network. tunnels. This feature enables automatic redirection of the user traffic to a standby tunnel when the primary tunnel goes down.

To enable L3 GREGeneric Routing Encapsulation. GRE is an IP encapsulation protocol that is used to transport packets over a network. tunnel group, you must:

configure a tunnel-group to group a set of tunnels.

enable tunnel keepalives on all the tunnel interfaces assigned to the tunnel-group, and

configure the session ACLAccess Control List. ACL is a common way of restricting certain types of traffic on a physical port. with the tunnel-group as the redirect destination.

To enable L2 GREGeneric Routing Encapsulation. GRE is an IP encapsulation protocol that is used to transport packets over a network. tunnel group, you must:

configure the member tunnel and add them to the appropriate VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN..

enable tunnel keepalives on the tunnel interface.

configure the tunnel-group and set the group type to L2, and

add the member tunnel to the group

 

You can configure up to 32 tunnel-groups on a managed device 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:

(host) [mynode] (config) #tunnel-group tgroup1

(host) [mynode] (config-tunnel-group)# mode l3

(host) [mynode] (config-tunnel-group)# tunnel 10

(host) [mynode] (config-tunnel-group)# tunnel 20

(host) [mynode] (config-tunnel-group)#preemptive-failover
