Description (partial)

Symptom:
EIGRP Router configured with wide metric updates ("metric version 64bit")
is sending classic updates, which will be ignored by peer. Peer will 
no longer add routes from that peer.

Conditions:
- Have configured "metric version 64bit" for the EIGRP process. 
- Have invalid values for "classic / wide metric" peers in "show eigrp interface"
to where the # of classic peers is > then the number of total peers.
