Hello,
I recreated official Cisco TShoot topology winthin GNS3.
Official Cisco post: [https://learningnetwork.cisco.com/thread/10965](https://learningnetwork.cisco.com/thread/10965)
This is what you get in GNS3:
Im sharing two GNS3 portable projects:

CCNP TSHOOT 300–135 Lab Exam Topology – 001 Initial Configuration.gns3project
- Contains only initial configuration to enable reachability between nodes.
- Everything is left as default, except DSW1 and DSW2 STP priority changed, switches are primary/secondary roots for specific vlans.
CCNP TSHOOT 300–135 Lab Exam Topology – 002 Basic Configuration.gns3project
- Based on previous initial configuration and adds following stuff to the table.
- Authentication for PPP line, R6 requires CHAP, R1 requires PAP.
- BGP authentication.
- Various OSPFv2 authentications configured.
- Various OSPFv3 authentications configured (using AH/ESP).
- Various EIGRP authentications configured.
- LACP priority settings changed, DSW1 and DSW2 are now in charge.
- Spanning-Tree mode changed to MST.
- VTPv3 used to synchronize MST Instance-to-VLAN mapping.
- Portfast enabled globally on ASW1 and ASW2 for all access operational ports.
- BPDUfilter enabled globally on ASW1 and ASW2 for all Portfast operational ports.
- BPDUguard enabled globally on ASW1 and ASW2 for all Portfast operational ports.
- UDLD enabled in aggresive mode for trunking interfaces on all switches.
- CDP disabled on ASW1 and ASW2 for all access client ports.
- DHCP snooping configured for VLAN 10 on ASW1.
- DSW1 and DSW2 are configured to accept DHCP requests with option 82 and 0.0.0.0 giaddr.
- DAI configured for VLAN 10 on ASW1.
- Port-security configured on ASW1 for client access ports, with sticky keyword.
- Errdisable automatic recovery from psecure-violation configured on ASW1.
- HSRP version changed to 2, authentication added, preempt reload delay added.
- HSRP priority is now bound to tracked object.

- uRPF configured on all routers.
In case you dont want to import full GNS3 project there are also shared running-configs in txt files for all nodes, thus you can take a look.
I hope this helps to someone, or at least saves you some time from creating topology from scratch.
