Absolutely! I used GNS3 for my CCIE study and there is very few features that you cannot test/lab out. 

Thank you for rating helpful posts!

I tried to do a debug crypto isakmp  on HUB

logging buffered 7

logging console 7

but can not see any debug log 

Can you post your "logging" configs here? Also, do you have "term mon" enabled?

Thank you for rating helpful posts!

I am able from spoke 1 ping GRE address (192.168.100.3) on spoke 2

but no logs in debug and under spoke1 there is no spoke 2 GRE address after ping

spoke1#sh ip nhrp
192.168.100.1/32 via 192.168.100.1
Tunnel1 created 00:12:57, never expire
Type: static, Flags:
