DHCP service in Router On a Stick
bouw /\/\/\ from scratch in packettracer
OPDRACHT:
- bereken eerst de subnetten:
- in address-space
10.45.106/24 (variable subnetting): - ADMINISTRATION - VLAN100 - 100 hosts
- ACCOUNTING - VLAN10 - 20 hosts
- SALES - VLAN20 - 20 hosts
- SUPPORT - VLAN30 - 10 hosts
- MANAGEMENT - VLAN40 - 10 hosts
- in address-space
-
bouw alles op in PT
S-0- FA0/11-20 in VLAN100
- FA0/1 trunk to VLAN10
- FA0/2 trunk to VLAN20
- FA0/3 trunk to VLAN30
- FA0/4 trunk to VLAN40
- Gi0/0 trunk to ROS (R1)
S1
- FA0/02-21 in VLAN10
S2
- FA0/02-21 in VLAN20
S3
- FA0/02-21 in VLAN30
S4
- FA0/02-21 in VLAN40
Alle switches en router VLAN88 voor SVI: laatste subnet - 14 adressen. voor configuratie,
R-O-S telkens laatste adres van alle subnetten als default gateway,

- een printer met MAC-address 01-02-03-0a-0b-0c op 10.45.106.111

Download bovenstaande oplossing:- corrigeer de default gateway in de dhcp pool van VLAN100
- vervolledig de configuratie van VLAN20
