Question What are the supported Layer 2 interworking stitching configurations? Answer These are the stitching options supported in Junos OS Release 9.3 and later: Layer 2 circuit into Layer 2 VPN NOTE: In Junos OS Release 9.4 and later, you can use an iw interface instead of an lt interface for this purpose.

Question What is the solution for interprovider Option B connection between LDP-based Layer 2 circuits and BGP-based Layer 2 VPNs? Answer As of Junos OS Release 9.3 and later, Layer 2 circuits with interworking iw0 interfaces can be manually stitched. If dynamic signaling is needed, use FEC 129 multisegment pseudowires if you are not using BGP-based Layer 2 VPNs
Question What are the Junos OS solutions for terminating <password> Layer 2 circuits into VPLS? Answer On an MX Series router, 48 Layer 2 circuits can be terminated into a single VRF, per each tunnel PIC. In Junos OS, <password> Layer 2 circuits can be terminated into VPLS by using logical tunnel (lt) interfaces
Answer The following are the Juniper Networks solutions for Metro Ethernet Forum (MEF) 6.1 Ethernet services definitions: Ethernet private line (EPL) and Ethernet virtual private line (EVPL) are emulated by Juniper Networks Layer 2 circuit and Layer 2 VPN configurations
Read David Wood's write-up on how to dimension the Router-layer links in metro-rings to take the best advantage possible of bypass wavelengths. This design problem is different when you have “open” routing protocols like OSPF or ISIS vs how to dimension the network with auto-bandwidth,...
