Lab IP Address Plan Campus Network Design & Operations Workshop The following diagram shows the layout of our network for the workshop. The two routers at the top are the NREN and these are connected to the workshop subnet. For the lab exercises, each group has been allocated the following address space for their campus: Campus Public IPv4 Private IPv4 IPv6 Campus AS Number 1 100.68.1.0/24 172.21.0.0/16 2001:DB8:1::/48 10 2 100.68.2.0/24 172.22.0.0/16 2001:DB8:2::/48 20 3 100.68.3.0/24 172.23.0.0/16 2001:DB8:3::/48 30 4 100.68.4.0/24 172.24.0.0/16 2001:DB8:4::/48 40 5 100.68.5.0/24 172.25.0.0/16 2001:DB8:5::/48 50 6 100.68.6.0/24 172.26.0.0/16 2001:DB8:6::/48 60 The following diagram shows the structure within each campus. Each campus is designed the same way, with a border and core router, and six switches shared over two buildings. You will be given details the addresses to use for the routers and switches as we work through the exercises but they will be allocated from these blocks: Network IPv4 IPv6 Router core 100.68.X.0/28 2001:DB8:X:0::/64 NAT Pool 100.68.X.32/28 N/A Servers 100.68.X.128/28 2001:DB8:X:1::/64 Loopbacks 100.68.X.240/28 2001:DB8:X:2::/64 Building 1 Management 172.2X.10.0/24 2001:DB8:X:10::/64 Building 1 Staff 172.2X.11.0/24 2001:DB8:X:11::/64 Building 1 Student 172.2X.12.0/24 2001:DB8:X:12::/64 Building 2 Management 172.2X.20.0/24 2001:DB8:X:20::/64 Building 2 Staff 172.2X.21.0/24 2001:DB8:X:21::/64 Building 2 Student 172.2X.22.0/24 2001:DB8:X:22::/64 You will need to replace 'X' with the number of your campus group! The following IPv4 address ranges have been assigned by the NREN for the links to the Border routers: Campus NREN Link Subnet NREN Router Address Campus Border Router Address 1 100.68.0.0/30 100.68.0.1 100.68.0.2 2 100.68.0.4/30 100.68.0.5 100.68.0.6 3 100.68.0.8/30 100.68.0.9 100.68.0.10 4 100.68.0.12/30 100.68.0.13 100.68.0.14 5 100.68.0.16/30 100.68.0.17 100.68.0.18 6 100.68.0.20/30 100.68.0.21 100.68.0.22 The following IPv6 address ranges have been assigned by the NREN for the links to the Border routers: Campus NREN Link Subnet NREN Router Address Campus Border Router Address 1 2001:DB8:100:1::/127 2001:DB8:100:1::0 2001:DB8:100:1::1 2 2001:DB8:100:2::/127 2001:DB8:100:2::0 2001:DB8:100:2::1 3 2001:DB8:100:3::/127 2001:DB8:100:3::0 2001:DB8:100:3::1 4 2001:DB8:100:4::/127 2001:DB8:100:4::0 2001:DB8:100:4::1 5 2001:DB8:100:5::/127 2001:DB8:100:5::0 2001:DB8:100:5::1 6 2001:DB8:100:6::/127 2001:DB8:100:6::0 2001:DB8:100:6::1 For completeness, the following addresses are used within the NREN itself. Note that the NREN’s IPv4 backbone addressing is shared with the classroom backbone. IPv4 IPv6 TR1 Loopback 100.68.0.251 2001:DB8:100:FF::251 TR2 Loopback 100.68.0.252 2001:DB8:100:FF::252 TR1 Ethernet Backbone 192.168.122.2/24 2001:DB8::2/64 TR2 Ethernet Backbone 192.168.122.3/24 2001:DB8::3/64 The NREN is running inside AS 65534.
