Interworking is a transforming function that is required to interconnect two heterogeneous
attachment circuits(ACs). Several types of interworking functions exist. The function that is used
would depend on the type of ACsbeing used, the type of data being carried, and the level of
functionality required. The two main Layer 2 VirtualPrivate Network (L2VPN) interworking
functions supported in Cisco IOS XE software are bridged and routedinterworking.Layer 2 (L2) transport over multiprotocol label switching (MPLS) and IP already exists for like-tolike ACs, suchas Ethernet-to-Ethernet or Point-to-Point Protocol (PPP)-to-PPP. L2VPN
Interworking builds on thisfunctionality by allowing disparate ACs to be connected. An interworking
function facilitates the translationbetween different L2 encapsulations.
