I have a practice skills exam I need some help with. It is implementing Inter-VLAN routing as well as subnetting. We are given the IP add of 192.168.50.0. We are then given VLAN 10 (30 host ips), VLAN 20 (6 host ips), VLAN 30 (60 host ips) and VLAN 99 (10 host ips/VLAN trunks). She wants us to subnet based on the hosts required for each VLAN. We must address for each of the following: S1 Vlan 99, S2 Vlan 99, R1 loopback, R1 Fa0/1.1, R1 Fa0/1.10, R1 Fa0/1.20 and R1 Fa0/1.99, then 3 host PC’s. The way she wants is it that I would subnet VLAN 30 then 10 then 99 then 10. If I need to subnet the VLANs first, how do I come about the S1 and S2 VLAN 99 addresses, as with the R1 loopback and R1 Fa0/1.99? Any help would be greatly appreciated! Thank you and I look forward to being a member on these boards.
