IS-IS Router Using Ethernet or TEB GRE Interfaces

This recipe demonstrates how to setup basic IS-IS routing between two nodes connected using either an Ethernet interface or a GRE interface in Transparent Ethernet Bridging (TEB) mode.

Warning

Due to the fact that IS-IS operates at L2, active IS-IS interfaces must be able to carry L2 information. Currently this is limited to Ethernet interfaces as well as GRE interfaces in Transparent Ethernet Bridging (TEB) mode.
