Configuring MPLS/VPN Support
How to Configure the MPLS Environment
If either VLAN or tunneling support is in default mode, skip the relevant step in the following procedure.
Step 1
From the SCE(config if)# prompt, type
Configures VLAN support to default mode.
From the SCE(config if)# prompt, type
Step 2
Disables all other tunneling protocol support.
All subscribers with VPN mappings must be cleared to change the tunneling mode. If the connection
Note
with the SM is down, use the no subscriber all with-vpn-mappings CLI command.
In addition, all VPN mappings must also be removed. This can only be done via the SM CLU (which
Note
means that the connection with the SM must be up).
From the SCE(config if)# prompt, type
Step 3
Enables the MPLS auto-learning mechanism.
