- Configuring IS-IS or MPLS Traffic for TCC Interfaces
Configuring IS-IS or MPLS Traffic for TCC Interfaces
Layer 2.5 VPNs on T-series, M120, and M320 routers support IPv4, IS-IS, and MPLS traffic types. By default, IPv4 traffic runs on T-series, M120, and M320 routers and over TCC interfaces. To configure IS-IS (ISO traffic) or MPLS traffic on Layer 2.5 VPNs, you must configure the same traffic type on both ends of the Layer 2.5 VPN.
To specify which traffic can run over a TCC interface, include the protocols statement with the appropriate value (inet, mpls, and iso) at the [edit interfaces interface-name unit logical-unit-number family tcc] hierarchy level:
- [edit interfaces interface-name unit logical-unit-number family tcc]
- protocols [ inet
iso mpls ];

Note: Layer 2.5 VPNs running on M-series routers support only IPv4 traffic. IPv6 is not supported on Layer 2.5 VPNs. |
When enabling ISO over a Layer 2.5 VPN that is configured on a CE Ethernet interface, you must also include the point-to-point statement at the [edit protocols isis interface interface-name] hierarchy level:
