EIGRP timers over WAN media default to 60 seconds. Neighborship will not
expire for up to 180 seconds. To verify your EIGRP neighborship do a "show
ip eigrp neighbor"

With regard to EIGRP, link type is dictated by the medium and speed. In this
case, Ethernet will be considered a high-speed, broadcast link regardless of
its use for LAN or WAN, so the hello/dead intervals should, by default, be
5/15 seconds.
