The goal is to practice using the basic commands of OSPF and standard ACLs. Please do the following configurations:

$1.-$ Configure the IP addresses as:

$-$ Host A: $10\mathrm{.}1\mathrm{.}1\mathrm{.}1/24.$ Gateway: $10\mathrm{.}1\mathrm{.}1\mathrm{.}3$

$-$ Host B: $10\mathrm{.}1\mathrm{.}1\mathrm{.}2/24.$ Gateway: $10\mathrm{.}1\mathrm{.}1\mathrm{.}3$

$-$ R$1$s G$0/0$: $10\mathrm{.}1\mathrm{.}1\mathrm{.}3/24$

$-$ Host C: $10\mathrm{.}3\mathrm{.}3\mathrm{.}3/25.$ Gateway: $10\mathrm{.}3\mathrm{.}3\mathrm{.}1$

$-$ R$1$s G$0/1$: $10\mathrm{.}3\mathrm{.}3\mathrm{.}1/25$

$-$ S$1$: $10\mathrm{.}2\mathrm{.}2\mathrm{.}1/24.$ Gateway: $10\mathrm{.}2\mathrm{.}2\mathrm{.}3$

$-$ S$2$: $10\mathrm{.}2\mathrm{.}2\mathrm{.}2/24.$ Gateway: $10\mathrm{.}2\mathrm{.}2\mathrm{.}3$

$-$ R$2$s G$0/0$: $10\mathrm{.}2\mathrm{.}2\mathrm{.}3/24$

$-$ R$1$s S$0/3/0$: $10\mathrm{.}4\mathrm{.}4\mathrm{.}1/30$

$-$ R$2$s S$0/3/0$: $10\mathrm{.}4\mathrm{.}4\mathrm{.}2/30$

Check that you can ping between hosts in the same subnet:

$-$ From Host A to Host B$.$

$-$ From Host C to R$1$s G$0/1$ interface.

$-$ From S$1$ to S$2.$

$-$ From R$1$s S$0/3/0$ interface to R$2$s S$0/3/0$ interface.

Note that you can$$t ping between hosts in different subnets because the routers don$$t have any entry in their routing table.

$2.$ Enable OSPF in all interfaces, both R$1$ and R$2($area $0),$ with only one subcommand in the OSPF configuration.

Check that the neighboring relationships have been created between R$1$ and R$2.$

Check that, after configuring OSPF, you can ping between hosts in different subnets.

$-$ From Host A to Host C$.$

$-$ From Host C to S$1.$

$-$ From Host A to S$1.$

$3.$ Configure ACL on the right routers, interfaces and directions based on these requirements:

$-$ Permit packets from S$1$ going to subnet of hosts A and B$.$

$-$ Deny packets from S$2$ going to subnet of host A and B$.$

$-$ Permit packets from S$2$ going to subnet of host C$.$

$-$ Deny packets from S$1$ going to subnet of host C$.$

After configuring ACL, check that:

$-$ You can ping from S$1$ to host A and B$,$ but not to host C$.$

$-$ You can ping from S$2$ to host C$,$ but not to hosts A and B$.$
