## Re: completing the attached table using a given topology

Hello sjo626,

you should at least add the network diagram in order to understand how the routers R1-R4 and the switches are inter connected.

Also the PCs Pc0-Pc1 to what routers are connected ?

The general guidelines are the following:

for IPv4 routing to work two routers or a router and a multilayer switch need to share a common IPv4 subnet between them.

For IPv6 there are the link local addresses that provide a common ground for communication on a link, but they are not routable so you still need to assign a routable unicast IPv6 subnet to each link.

Hope to help

## Re: completing the attached table using a given topology

Hello sjo626,

this looks like a homework assigned to you by your teacher in a Network Academy course or a university course..

The exercise is made of  nine configuration tasks involving IPv4 and IPv6 addressing, L2 port security and so on.

The network diagram provides you with all the info to fill the table.

R1:

R1-R3 can use serial 1 and must use IPv4 subnet 1.1.X.0/30

R1  serial 1 : IPv4 address 1.1.X.1 255.255.255.252

R1-R2 can use serial 2 on R1 side and must use IPv4 subnet 1.1.x.4/30

So R1 serial 2 IPv4 address 1.1.X.5 255.255.255252

R1 LAN interface Fas0  belongs to 10.20.x.32/27 and must take the first available IPv4 address

R1 Fas0 -> 10.20.x.33/27

Sw-1 will take the 10.20.x.34/27.

The exercise requires you to create a Vlan with Vlan-id equal to the third octet X or ? in your exercise.

Let us suppose X = 11 on R1 / S1.

Sw-1

vlan 11

name Management

exit

int vlan 11

no shut

configure each switchport as

interface fas0/1

switchport

switchport mode access

switchport access vlan 11

About IPv6 addressing on LAN interfaces a note is needed here: we usually use eui-64 addresses that fill the host portion of the address with 64 bits derived from the MAC address on the interface itself.

Here, you are requested to use the first available address in each IPv6 subnet on LAN interfaces on router devices.

So

int fas0

ipv6 address 2002:DB8:?:A::1 /64 meaning the last 64 bits are 0000:0000:0000:0001 in hexadecimal.

You can easily follow the example for all the other routers and switches and you can post your addressing table here.

However, about IPv6 addressing on LAN you will need to discuss with your teacher if use of eui-64 is an acceptable solution or not.

Hope to help
