@evanmckay927 hello,

1. you configured router interfaces as listed. 

2. for switches go to configuration mode and use 'int vlan 10' and configure the relevant IP for VLAN 10 as per your list. do same for vlan 1 and 20 for both switches.

3. configure interface trunk mode between interfaces connecting routers and switches

4. configure relevant VLAN in switch port where PCs are connected as per your list. port need to be access mode.

5. configure correct IPs in the PCs

Dear @evanmckay927 

a. DOTq configuration should correspond to VLAN number that is used on the switch.

b. Allow ALL vlan on the trunk on the switch by removing the "allowed vlan 10,20"

c. Configure "ip default-gateway <ip address of router>" so the switch itself can reach router as its gateway (usually used for management purpose)

d. Configure corresponding VLAN on the switch port where the PC (or end device) is connected.

=== @router

interface GigabitEthernet0/0.10
encapsulation dot1Q 10                                 <--------a.
ip address 201.10.15.9 255.255.255.248

interface GigabitEthernet0/0.20
encapsulation dot1Q 20
ip address 201.10.15.17 255.255.255.248

=====in switch1

interface 0/1
no switchport trunk allowed vlan 10,20                 <----b
switchport mode trunk

interface FastEthernet0/3
switchport access vlan 10                   <---- d
switchport mode access
exit

interface f0/10
no switchport trunk allowed vlan 10,20
switchport mode trunk
exit

interface vlan 1
no shutdown
exit

ip default-gateway 201.10.15.1        <----c

=== switch2

interface f0/6
switchport mode access
switchport access vlan 20
exit

interface f0/10
switchport mode trunk

interface vlan 1
no shut
ip address 201.10.15.3 255.255.255.248
exit

ip default-gateway 201.10.15.1

Follow also as what is suggested by Kasun in configuring vlan interface (or assigning multiple IP addresses with its corresponding vlan interface) on switch1 and switch2.
