Task 1

Configure IPv6 addresses between SW2 and BB2 as follows:

• SW2 (Vlan 208): 2001:0:0:D0::8/64 
• BB2 (Fa0/0): 2001:0:0:D0::FE/64

Task 2
In BB2 configure four loopbacks using the following addresses:

• Loopback 0: 2001:2:2:0::1/64
• Loopback 1: 2001:2:2:1::1/64
• Loopback 2: 2001:2:2:2::1/64
• Loopback 3: 2001:2:2:3::1/64

Task 3

Enable RIPng with the identifier 'CCIE' between SW2 and BB2. Ensure that SW2 advertises only one learned from BB2. All other RIPng devices should be able to reach more specific prefixes advertised by BB2.
