Hi Experts,
I have network connected like this: R1(Fa0/0) - (Fa0/0)R2
R1 Fa0/0 interface is configured for ip mtu 1498.
Now sending a ping with packet size of 1500 from R1 to R2.
The packet from R1 to R2 will be fragmented into 2 packets because of the ip MTU.
How will be reply packet from R2 to R1. How R2 comes to know that R1 has a lesser mtu size than its default value 1500 bytes?
Will the return reply packet be fragmented?
