We need to enable the routing on the WAN routers as follows:

WAN Router $1$

$-$ RIP Protocol

$-$ Network $10\mathrm{.}0\mathrm{.}0\mathrm{.}0$

WAN Router $2$

$-$ RIP Protocol

$-$ Network $10\mathrm{.}0\mathrm{.}0\mathrm{.}0$

$-$ Network $30\mathrm{.}0\mathrm{.}0\mathrm{.}0$

Edge Router $2$

$-$ RIP Protocol

$-$ Network $30\mathrm{.}0\mathrm{.}0\mathrm{.}0$

$-$ Network $192\mathrm{.}168\mathrm{.}1\mathrm{.}0$

Question $13$ Verify the end$-$to$-$end connectivity of the network $($from LAN $1$ to LAN $2)$ by

issuing ping and trace route commands. You might not be able to access LAN$1$ from LAN$2$ as

the wireless router $($edge router $1)$ does not advertise the internal $172\mathrm{.}16\mathrm{.}1\mathrm{.}0$ network. However,

accessing LAN $2$ from LAN $1$ should work fine if all the settings are correct.
