I have routers as below
R1-R2(CE1)--R3(PE1)--R5(CE2)
R1 is using only OSPF, r2 is using ospf/BGP, R5 is using OSPF/BGP
in R2 OSPF process, there is a command: OSPF default information originate
in R5,BGP process, there is a command: BGP default information originate
so my question is R1 will receive default route from R2 or r5?
