You can hold the rest for future expansion or recombine them for a new, larger subnet: 00010000 = .16/30 00010100 = .20/30 00011000 = .24/30 00011100 = .32/30 . . . 00111000 = .56/30 00111100 = .60/30 The first four of these can be combined into the following: 00010000 = .16/28 The rest of the /30 subnets can be combined into two /28 networks: 00100000 = .32/28 00110000 = .48/28 Or these two subnets can be combined into one larger /27 network 00100000 = .32/27 Going back to the original table you now have the following: 00000000 = .0/26Cannot use because it has been subnetted00000000 = .0/30Network E00000100 = .4/30Network F00001000 = .8/30Network G00001100 = .12/30Network H00010000 = .16/28Future Growth00100000 = .32/27Future Growth01000000 = .64/26Network ATable is correctFrom thisPoint forward Figure Corrections Page 37 Figure 4-4 should read 4-1 Page 38 Figure 4-5 should read 4-2 Page 64 Figure 6-5 should read 6-1 Page 78 Figure 8-7 should read 8-1 Page 87 Figure 9-8 should read 9-1 Page 98 Figure 10-9 should read 10-1 Page 121 Figure 12-2 should read 12-1 Page 132 Figure 13-3 should read 13-1 Page 148 Figure 14-4 should read 14-1 Page 153 Figure 14-5 should read 14-2 Page 162 Figure 15-6 should read 15-1 Figure 15-7 should read 15-2 Page 163 Figure 15-8 should read 15-3 Figure 15-9 should read 15-4 Page 164 Figure 15-10 should read 15-5 Figure 15-11 should read 15-6 Page 165 Figure 15-12 should read 15-7 Page 166 Figure 15-13 should read 15-8 Figure 151-14 should read 15-9 Page 167 Figure 15-15 should read 15-10 Figure 15-16 should read 15-11 Page 168 Figure 15-17 should read 15-12 Page 169 Figure 15-18 should read 15-13 Figure 15-19 should read 15-14 Page 170 Figure 15-20 should read 15-15 Page 171 Figure 15-21 should read 15-16 Figure 15-22 should read 15-17 Page 172 Figure 15-23 should read 15-18 Page 173 Figure 15-24 should read 15-19 Figure 15-25 should read 15-20 Page 174 Figure 15-26 should read 15-21 Figure 15-27 should read 15-22 Page 175 Figure 15-28 should read 15-23 Figure 15-29 should read 15-24 Page 176 Figure 15-30 should read 15-25 Figure 15-31 should read 15-26 Page 177 Figure 15-32 should read 15-27 Figure 15-33 should read 15-28 Page 178 Figure 15-34 should read 15-29 Figure 15-35 should read 15-30 Page 179 Figure 15-36 should read 15-31 Figure 15-37 should read 15-32 Page 180 Figure 15-38 should read 15-33 Figure 15-39 should read 15-34 Page 181 Figure 15-40 should read 15-35 Figure 15-41 should read 15-36 Page 228 Figure 23-3 should read 23-1 Page 233 Figure 24-4 should read 24-1 Page 254 Figure 26-1, first Network listing: should read Network 172.16.10.0/24 Page 261 Figure 27-2 should read 27-1 Page 280 Figure 28-3 should read 28.1 Page 17 The Enhanced Bob Maneuver Last line reads: 126 62 30 14 6 4 N/A Number of Valid Subnets Last line should read: 126 62 30 14 6 2 N/A Number of Valid Subnets Page 32 Figure 3-2 chart headings Reads: /21 /22 /23 /21 Should read: /21 /22 /23 /24 Page 33 Figure 3-3 char headings Reads: /21 /22 /23 /21 Should read: /21 /22 /23 /24 Page 118 First NOTE Reads: This method is the only way to configure extended-range VLANs (VLAN IDs from 100 to 4094).
