Exercise 6 |
1. (2) Suppose that a three segment Ethernet is connected by two transparent
routers, A and B. What happens on the Ethernet network when transparent bridge C
is added?
2. (3) Use Figure 5-13 on page 363 of the text for network. Assuming
that each router has a table containing destination router/port entries
that reflects that the best path to a destination router is through
port (e.g. D would have an entry for destination B of B/C, packets
must go through C to reach B). What is the router table for D using link
state routing?
3. (1) Use Figure 5-15 on page 367. What is the router path
from 1A to 5A?
4. (2) Use Figure 5-6 on page 352. How many packets are generated by a broadcast from B, using
a) (1) reverse path forwarding (assume the preferred path
follows the sink tree)?
b) (1) sink tree?
5. (3) Give the tree built by reverse path forwarding for a broadcast from I.
