I labbed it up, and this is the answer

for "network 1.1.1.1 255.255.255.255"

-Eigrp

show run | beg router eigrp 100 shows " network 1.1.1.1 0.0.0.0"

and sh ip protocol shows only interface with ip address "1.1.1.1" is chosen by
the eigrp process

-OSPF

show run | beg router ospf 100 shows " network 1.1.1.1 0.0.0.0 area 0"

and sh ip protocol or sh ip ospf int brief shows only interface with ip
address "1.1.1.1" is chosen by the ospf process

for "network 0.0.0.0 255.255.255.255"

-Eigrp

show run | beg router eigrp 100 shows " network 0.0.0.0"

and sh ip eigrp topo shows all interfaces are chosen by the eigrp process

-OSPF

show run | beg router ospf 100 shows " network 0.0.0.0 255.255.255.255 area
0"

and sh ip ospf int brief shows all interfaces are chosen by the ospf process.
