• All routers in the internetwork that must exchange EIGRP routing updates must have the same autonomous system number. Configuring EIGRP network network-number [ wildcard-mask ] network network-number [ wildcard-mask ] • Identifies attached networks participating in EIGRP. • wildcard-mask : An inverse mask used to determine how to read the address. The mask has wildcard bits, where 0 is a match and 1 is “don’t care.” Router(config)# Router(config-router)#
