Configuring ATM Over MPLS Trunks
About ATMoMPLS Trunks
About ATMoMPLS Trunks
ATMoMPLS trunks support a multiservice MPLS core solution by enabling
connection of Lucent ATM switches to MPLS core networks. In this implementation,
the MPLS core simulates a series of virtual trunks that connect to the ATM network
islands. The virtual trunks consist of ATM circuits that are mapped to MPLS label
switched paths (LSPs). The MPLS LSPs are used to tunnel data between the ATM
networks (Figure 8-2).
Figure 8-2. Multiservice MPLS Core Solution
This feature is designed to provide interoperability with Juniper T-series (T640 &
T320) routers running JUNOS Release 6.4 or above.
Management of the ATM network, which is distributed over the MPLS core, works in
the same way as management of any ATM network. Configuration and management
of the Lucent Trunk VPN between the two MPLS Juniper Label Edge Routers (LERs)
is accomplished using management software supplied by the MPLS LER switch
vendor.
