Q. Difficulties in Internetwork Communication?
- Data arrive at interface f1 of s1
- How does s1 know that they must be sent out from interface f3?
- There is no provision in the data link or else Physical layer to help s1 to select correct decision.
- Because the frame contains the MAC Address of A (Source) and
- The MAC Address of S1 (destination)
For LAN (or) WAN
- Delivery means carrying the frame through one link, not beyond
