I troubleshoot this yesterday for more than three hours I was trying to let R6 communicate with BB3 while native vlan option is configured under the interfaces (SW1 and R6) without enabling the vlan dot1q tag native globally but it was not working.
After all, I changed the router itself with more modern one (2600XM) and once I try it , it start working without any problem ,
In my lab R6 is 3620 with two Ethernet ports and is loaded with the IOS 12.2(37) , here is the error message I am getting out of it
IP ARP: sent req src 204.12.1.6 0010.7b96.c921,
dst 204.12.1.254 0000.0000.0000 Ethernet0/0.263
IP ARP rep filtered src 204.12.1.254 0000.0c09.f442, dst 204.12.1.6 0010.7b96.c921 wrong cable, interface Ethernet0/0.
IP ARP throttled out the ARP Request for 204.12.1.254.
Thanks to you all

Switch(config)#vlan dot1q tag native
Of course, ISL seems to be the simpler solution.

my interpretation of your task is:
"All traffic sent over this trunk should be tagged with a VLAN header" =>
use ISL encapsulation
"Do not use Dynamic Trunking protocol over this link" => switchport
nonegotiate
interface fa0/13
switchport trunk encapsulation isl
switchport mode trunk
switchport nonegotiate
HTH,

The previous task states :
Configure a trunk between Sw1s interface F0/13 and Sw2s interface F0/13
All traffic sent over this trunk should be tagged with a VLAN header
Do not use Dynamic Trunking protocol over this link
SW2-------TRUNK--------SW1------dot1q(native 263)------R6
