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 default vlan and press Enter.
Configures VLAN support to default mode.
Step 2 From the SCE(config if)# prompt, type no IP-tunnel and press Enter.
Disables all other tunneling protocol support.
Note All subscribers with VPN mappings must be cleared to change the tunneling mode. If the connection
with the SM is down, use the no subscriber all with-vpn-mappings CLI command.
Note In addition, all VPN mappings must also be removed. This can only be done via the SM CLU (which
means that the connection with the SM must be up).
Step 3 From the SCE(config if)# prompt, type MPLS VPN auto-learn and press Enter.
Enables the MPLS auto-learning mechanism.
Configuring the SCE Platform for MPLS/VPN Support
• Defining the PE Routers, page 13-12
• Configuring the MAC Resolver, page 13-14
• Monitoring the MAC Resolver, page 13-15
There are three main steps to configure the SCE platform for MPLS/VPN support:
1. Correctly configure the MPLS tunneling environment, disabling all other tunneling protocols,
including VLAN support. (see How to Configure the MPLS Environment, page 13-12)
2. Define all PE routers, specifying the relevant interface IP addresses necessary for MAC resolution
(see Defining the PE Routers, page 13-12.)
3. Configure the MAC resolver (see Configuring the MAC Resolver, page 13-14.)
