Layer 2 services over GRE tunnel interfaces with IPv6 transport

Junos OS supports Layer 2 Ethernet services over GRE interfaces with IPv6 traffic. After GRE encapsulates the packets, it redirects them to an intermediate host, where they are de-encapsulated and routed to their final destination. Support for bridging over GRE enables you to configure bridge domain families on gr- interfaces and also enable integrated routing and bridging (IRB) on gr- interfaces. To configure the bridge domain family on gr interfaces, include the family bridge statement at the [edit interfaces gr-fpc/pic/port unit logical-unit-number] hierarchy level.
