Branch 1

router eigrp 1

network 172.16.0.0

no auto-summary

Branch 2

router eigrp 1

network 192.168.3.0

no auto-summary

Branch 3

router eigrp 1

network 172.16.0.0

no auto-summary

Note that Branch 2 has no network in the 172.16.x.x range. For the routers to exchange EIGRP routes you must include a "network x.x.x.x" entry under the EIGRP config for the WAN interface as well eg.

lets say B1 connected to B2 by a subnet 192.168.12.0.

B1 address is 192.168.12.1

B2 address is 192.168.12.2

In addition to the config above you would need to add

Branch 1

router eigrp 1

network 172.16.0.0

network 192.168.12.0

no auto-summary

Branch 2

router eigrp 1

network 192.168.3.0

network 192,168.12.0

no auto-summary
