Topology

Configure IPv4 and IPv6 between the two routers.

Tasks
Reference Topology Diagram and table. Configure IPv4 and IPv6 between the two routers.
Task 1:
- Configure R1 with the first usable host IP address in the IPv4
network.
- Configure R2 with the last usable host IP address in the IPv4
network.
- Verify connectivity using ping.
Task 2:
- Do not assign the subnet router anycast address to either router.
- Configure R1 with the first usable host IP address in the IPv6
network.
- Configure R2 with the last usable host IP address in the IPv6
network.
- Verify connectivity using ping.
Correct Answer:
Task 1: Configure IPv4 between R1 and R2
From the table, the IPv4 subnet is 192.168.168.192/28. This gives us 16 total IP addresses, with
14 usable host IPs in the range 192.168.168.193 to 192.168.168.206. The first usable address is
192.168.168.193, and the last usable address is 192.168.168.206.
R1 Configuration (First Usable IPv4 Address):
R1(config)# interface Ethernet0/1
R1(config-if)# ip address 192.168.168.193 255.255.255.240
R1(config-if)# no shutdown
R2 Configuration (Last Usable IPv4 Address):
R2(config)# interface Ethernet0/1
R2(config-if)# ip address 192.168.168.206 255.255.255.240
R2(config-if)# no shutdown
Verify IPv4 Connectivity:
From R1, ping R2's IP address to ensure connectivity:
R1# ping 192.168.168.206
Task 2: Configure IPv6 between R1 and R2
From the table, the IPv6 subnet is 2001:db8:12::/125. This provides 8 addresses, with the range
2001:db8:12::1 to 2001:db8:12::6 as usable addresses. The first usable address is
2001:db8:12::1, and the last usable address is 2001:db8:12::6.
R1 Configuration (First Usable IPv6 Address):
R1(config)# interface Ethernet0/1
R1(config-if)# ipv6 address 2001:db8:12::1/125
R1(config-if)# no shutdown
R2 Configuration (Last Usable IPv6 Address):
R2(config)# interface Ethernet0/1
R2(config-if)# ipv6 address 2001:db8:12::6/125
R2(config-if)# no shutdown
Verify IPv6 Connectivity:
From R1, ping R2's IPv6 address to ensure connectivity:
R1# ping ipv6 2001:db8:12::6
IPv4 Addressing: The subnet 192.168.168.192/28 provides 16 IP addresses, with the first usable being 192.168.168.193 (assigned to R1) and the last usable being 192.168.168.206 (assigned to R2).
IPv6 Addressing: The subnet 2001:db8:12::/125 provides 8 addresses, and the first usable is
2001:db8:12::1 (assigned to R1) and the last usable is 2001:db8:12::6 (assigned to R2).
Both IPv4 and IPv6 configurations are done without using the subnet router anycast address.
