Topology


Tasks

Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.180.0/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:acca::/48 subnet.

1. 
   Using Ethernet0/1 on routers R1 and R2, configure the next usable /28 from the 192.168.180.0/24 range. The network 192.168.180.0/28 is unavailable.
   
2. 
   For the IPv4 /28 subnet, router R1 must be configured with the first usable host address.
   
3. 
   For the IPv4 /28 subnet, router R2 must be configured with the last usable host address.
   
4. 
   For the IPv6 /64 subnet, configure the routers with the IP addressing provided from the topology.
   
5. 
   A ping must work between the routers on the IPv4 and IPv6 address ranges.
   

^A. Solution


Task 1 + Task 2 + Task 3

The network 192.168.180.0/28 is unavailable so the next subnet is 192.168.180.16/28 (increment: 16). This subnet ranges from 192.168.180.16 to 192.168.180.31.

Therefore the first usable host address is 192.168.180.17/28 the the last usable host address is 192.168.180.30/28. We will them for two E0/1 interfaces:

R1(config)#interface e0/1

R1(config-if)#ip address 192.168.180.17 255.255.255.240 R1(config-if)#no shut

R2(config)#interface e0/1

R2(config-if)#ip address 192.168.180.30 255.255.255.240 R2(config-if)#no shut


Task 4.

On R1:

R1(config-if)#ipv6 address 2001:db8:acca::1/64 On R2:
R2(config-if)#ipv6 address 2001:db8:acca::2/64 Task 5.
R1#ping 192.168.180.30
.!!!!
R1#ping ipv6 2001:db8:acca::2/64
!!!!!
