Consider the figure below in which, +--+ +--+ +--+ +--+ +--+ +--+ TH| |H2| | H41 H51 | H81 | H91 +--+ +--+ +--+ +--+ +--+ +--+ 11 E1 14 | E4 15 | E5 18 E8 19 | E9 I 1 1 I 1 1 1 1 1 1 I 1 +-+ +-+ + +-+ LAN 1 1 LAN 2 1 1 LAN 3 1 +---+ 1 | 16 +---+ 17 | +----| B|----+ +---- R----+ E2 +---+ E3 E6 +---+ E7 B is a bridge. Its filtering table is initially empty. R is an IP router. HO, HI, H4, H5, H8 & H9 are hosts. 10, 11, 14, 15, 16, 17, 18 & 19 are 32-bit IP (interface) addresses, as shown. EO, E1, E, ....., E9 are 48-bit MAC (interface) addresses, as shown. Suppose host H4 sends an IP packet to host H9. This packet will, of course, be encapsulated in an Ethernet frame. a) What will the source Ethernet address in the header of that frame be as the frame traverses LAN 2? b) What will the destination Ethernet address in the header of that frame be as the frame traverses LAN 2? c) What will the destination IP address in the header of the encapsulated packet be as the frame traverses LAN 2? d) What will the source Ethernet address in the header of the frame encapsulating the packet be, as that frame traverses LAN 3? e) What will the destination Ethernet address in the header of that frame be as the frame traverses LAN 3? f) What will the source IP address in the header of the encapsulated packet be as the frame traverses LAN 3? g) Bridge B will, of course, receive the frame off of LAN 2. Will it transmit a copy of it on LAN 1? h) Now, suppose that H9 sends a reply back to H4. Will bridge B transmit a copy of that reply on LAN 1? i) After it receives that reply, suppose that H4 now sends a packet to H5. Will bridge B transmit a copy of the frame encapsulating that packet on LAN 1 j) Will router R forward the packet of the part (1) above to LAN 3
