Configuring ATM Over MPLS Trunks
Configuration Overview
Configuration Overview
Implementing the multiservice MPLS core solution involves the following tasks:
• “Configuring the MPLS LERs” below.
To learn more about setting up the MPLS core routers, refer to the JUNOS
Internet software documentation.
• “Configuring ATMoMPLS Trunks” on page 8-13
Configuring ATMoMPLS on the Lucent ATM edge switches is described in this
chapter.
Configuring the MPLS LERs
Before you configure ATMoMPLS trunks on Lucent ATM switches, you should
configure the MPLS LERs. This involves two key configuration tasks:
1. Create MPLS tunnels between the LERs, specify bandwidth requirements for the
tunnels, and select path protection attributes for the backup tunnels.
2. Provision the Lucent Trunk VPN on the ATM interfaces of the MPLS LER. The
two endpoints of the Lucent Trunk VPN are created by specifying a Trunk ID that
is local to the two interfaces. Bandwidth must also be allocated for the four ATM
QoS classes.
Note – To learn more about creating MPLS tunnels and provisioning the Lucent
Trunk VPN on the MPLS core routers, refer to the JUNOS Internet software
documentation. To obtain the most current versions of Juniper Networks technical
documents, refer to the product documentation page on the Juniper Networks Web
