In 2004, [[Radia Perlman]] proposed using link-state routing for [[layer 2]] frame forwarding with devices called [[Routing Bridge|routing bridge]]s or Rbridges. The [[Internet Engineering Task Force]] has standardized the [[TRILL (Computer Networking)|transparent interconnection of lots of links]] (TRILL) protocol to accomplish this.<ref>{{citation |rfc=7176 |title=Transparent Interconnection of Lots of Links (TRILL) Use of IS-IS|date=May 2014|last1=Eastlake 3Rd|first1=Donald E.|last2=Senevirathne|first2=Tissa|last3=Ghanwani|first3=Anoop|last4=Dutt|first4=Dinesh|last5=Banerjee|first5=Ayan}}</ref>

More recently, this hierarchical technique was applied to [[wireless mesh network]]s using the [[optimized link state routing protocol]] (OLSR). Where a connection can have varying quality, the quality of a connection can be used to select better connections. This is used in some [[Adad hoc routing protocol list|routing protocols]]s that use radio frequency transmission.

In 2012, the [[IEEE]] completed and approved the standardization of the use of IS-IS to control [[Ethernet]] forwarding with [[IEEE 802.1aq]] shortest path bridging (SPB).
