* Advertising a default route out one interface:
ip summary-address eigrp [AD] 0.0.0.0 0.0.0.0
* To see if a neighbor is configured as STUB:
show ip eigrp neighbors [detail] => look for ‘CONNECTED SUMMARY’
* On frame-relay multipoint interfaces disable split-horizon.
* External EIGRP routes AD (admin distance = 170) can NOT be changed on per prefix basis.
* Metric weight values:
1 0 1 0 0 = Default
0 0 1 0 0 = Only DLY
1 0 0 0 0 = Only BW
3 0 1 0 0 = BW has 3 times more weight reference than DLY
 
* Metric formula:
Metric = ((107 / BW) + (DLY/10) ) * 256
