The OSPFv3 Dynamic Interface Cost Support feature extends Point-to-Point Protocol over Ethernet 
(PPPoE) to enable a router or radio to query or report link-quality metric information. Cisco routers have 
been enhanced so that Open Shortest Path First version 3 (OSPFv3) or Enhanced Interior Gateway 
Routing Protocol (EIGRP) can factor link quality metrics into route cost calculations. 

The OSPFv3 Dynamic Interface Cost Support feature provides enhancements to the OSPFv3 cost metric 
for supporting Mobile Ad Hoc Networks.

Configuration information is included in the “Mobile Ad Hoc Networks for Router-to-Radio 
Communications” module of the Cisco IOS IP Mobility Configuration Guide, Release 12.4T,
