TX Matrix Plus Router Internal Ethernet Interfaces
On a TX Matrix Plus router, the Routing Engine (RE-TXP-SFC) and Control Board (TXP-CB) function as a unit, or host subsystem. For each host subsystem in the router, the Junos OS automatically creates two internal Ethernet interfaces, ixgbe0 and ixgbe1, for the two 10-Gigabit Ethernet ports on the Routing Engine.
When you enter the show interfaces command on a TX Matrix Plus router, the internal Ethernet interfaces (and logical interfaces) are displayed:
user@host> show interfaces ?... ixgbe0 ixgbe0.0 ixgbe1 ixgbe1.0 ...
