A non$-$Cisco switch configured with two VLANs: $2$ and $100.$ VLAN $2$ is a $192\mathrm{.}168\mathrm{.}10\mathrm{.}0/24$ network, and VLAN $100$ is a $172\mathrm{.}16\mathrm{.}20\mathrm{.}0/24$ network. This switch is not $802\mathrm{.}1$Q compliant. How can we route between these VLANs given that we have a Cisco router with $3$ available interfaces: FastEhternet $0/1,1/0,$ and $1/1?$
