$1.$ Using the network diagram below, complete the virtual circuit tables $($next page$)$ for all switches after the following connections have been established.

a$.$ Add rows to each virtual circuit table as needed

b$.$ Assume that the sequence of connections is cumulative; that is$,$ the first connection is still up when the second connection is established and so on$.$

c$.$ Assume that the VCl assignment always picks the lowest unused VCI on each link, starting with zero.

Connections to be made:

Connection $1.$ Host A connects to Host E

Connection $2.$ Host B connects to Host E

Connection $3.$ Host $\backslash ($ C $\backslash )$ connects to Host $\backslash ($ F $\backslash )$

Connection $4.$ Host F connects to Host A

Connection $5.$ Host E connects to Host C

Connection $6.$ Host D connects to Host B B$1$ Virtual Circuit Table
