HI Expert, I want to confirm a concept of command ip default-gateway in router or switch. Here is config. and two routers R2 and R3 are connected with each other.


interface Ethernet1/0
 ip address


no ip routing

interface Ethernet1/0
 ip address

I tested it and the result is that R2 can still ping R3. My question is why R2 can ping R3 successfully since R3 is in no ip routing mode and did not use the command ip default-gateway ? In another word, how can R3 send the ping packet back to R2 due to R3 configuration ? Thank you
