Configuring ATM Over MPLS Gateway Solution on CBX 3500
Configuring a Layer 2 Tunnel Over MPLS Core Network
Table 9-5. Modify Switch: MPLS Tab Fields
Field Description
MPLS Admin Status Set the MPLS Admin Status as follows:
• Up – (default) Activates MPLS on the switch. 
• Down – Saves the configuration in the database without 
activating MPLS on the switch.
IP Vpn Not available for this release.
LSR ID The LSR ID is the valid IP address for local and remote ends of the 
Layer 2 tunnel.
Select an available LSR ID from the pull-down list box. This is the 
LSR router ID used by RSVP-TE. This field must be set before any 
other MPLS configuration can be done on this switch. Once any 
MPLS configuration occurs (for instance, MPLS tunnels or LDP 
sessions) this field may not be changed unless the other MPLS 
configuration is deleted. 
This field will not be available if the User Configured LSR ID box 
is checked.
User Configured 
LSR ID
To enter the IP address of the LSR, check the User Configured 
LSR ID box, then enter the IP address of the LSR ID assigned to 
this switch.
Static Label Max 
(0 or 16-65535)
The static label maximum is defined within a label range of zero 
(0)-65535. Zero (0) - 16 is reserved for MPLS.
Set the maximum label to be used by static configuration of PSN 
tunnels, PWE3 and Layer 2 tunnels. 
The range of labels between the maximum value set and 65535 will 
be used for RSVP-TE and LDP signaling.
