I could not get the IP Cloud to work, so I removed the IP cloud and made a direct link from R1 to Server

8.3.1.2 Packet Tracer - EIGRP IPv4 and IPv6 Skills Integration Challenge

8.3.1.2 Packet Tracer - EIGRP IPv4 and IPv6 Skills Integration Challenge

This one took me a long time because I could not summirize the ipv6 addresses. I had to go do some practice exercises with IPv6 CIDR (https://www.ultratools.com/tools/ipv6CIDRToRange) before I finally got on the right track.

Here is how I did my summary for IPv6

Networks
2001:DB8:1:1:A100::/72
2001:DB8:1:1:A200::/72
2001:DB8:1:1:A300::/72
2001:DB8:1:1:A400::/72

The normal network range for ipv6 is /64, so here 12 extra bits are borrowed

2001:DB8:1:1: = 16+16+16+16 = 64
A100:: /= 16+16+1616
A100 through A400 = 4 (1010)+4 (1through 4) +4 (0000)+4 (0000)   = 16 bits
Address A100 = 1010 0001 0000 0000
Address A200 = 1010 0010 0000 0000
Address A300 = 1010 0011 0000 0000
Address A400 = 1010 0100 0000 0000
The common bits in this address are 1010 0, which is 1+1+1+1+1 =5 bits

2001:DB8:1:1: = 64 bits
+ 5 bits of 1010 0...
64 bits + 5 bits = 71 bits, starting with 0

Summary address is 2001:DB8:1:1:A000::/71

For networks
2001:DB8:1:1:BB80::/76
2001:DB8:1:1:BB90::/76
2001:DB8:1:1:BBA0::/76
2001:DB8:1:1:BBB0::/76

If the network mask is 76, and the normal network range for ipv6 is /64, so here 10 extra bits are borrowed
2001:DB8:1:1 = 64 bits
BB80::/= 16+16+16+16 bits
BB80  through BBB0 = 4 (B) + 4(B) + 4 (???) + 4 (0) = 16 bits

BB80 = 1011 1011 1000 0000
BB90 = 1011 1011 1001 0000
BBA0 = 1011 1011 1010 0000
BBB0 = 1011 1011 1011 0000
The common bits for this address are 1011 1011 10, which are 4+4+2 = 10 bits

2001:DB8:1:1 = 64 bits
1011 1011 10 = 10 bits, starting with 1 0  in positions 8 and 4, which means that the summary network will start with 80
64 bits + 10 bits = 74 bits

Summary address 2001:DB8:1:1:BB80::/74
