Options
The following options are available:
• traffic-engineering skip (default)—Use when all IP addresses are unique and MPLS labels are not
mandatory for routing.
• VPN skip —Use when all IP addresses are unique, but MPLS labels are mandatory for routing.
• VPN auto-learn —Use in an MPLS/VPN environment where auto-learning is required due to the
existence of private IP addresses and/or VPN based subscribers.
When this option is configured, both ip-tunnel and VLAN must be set to their default values.
Use the VPN keyword when the labels are mandatory in the traffic, otherwise use traffic-engineering
(default).
Note that using the VPN value incurs a performance penalty.
The MPLS VPN auto-learn option is required in an MPLS/VPN environment.
Step 1 From the SCE(config if)# prompt, type mpls {traffic-engineering skip|vpn skip|vpn auto-learn} and
press Enter.
Specify the desired MPLS mode.
Configuring the MPLS Environment: Example
The following example selects the MPLS/VPN tunnel environment.
SCE(config if)#mpls vpn auto-learn
