Release Information

Statement introduced in Junos OS Release 8.3.


For Layer 2.5 VPNs on T Series, MX Series, M120, and M320 routers support, configure IS-IS (ISO traffic) or MPLS traffic to traverse a TCC interface. By default, IPv4 (inet) traffic runs on T Series, MX, Series, M120, and M320 routers and over TCC interfaces. You must configure the same traffic type on both ends of the Layer 2.5 VPN.


Some platform and FPC combinations can not pass TCC encapsulated ISO traffic. See Platforms/FPCs That Cannot Forward TCC Encapsulated ISO Traffic for details.
