DvR

[Maryam]

How to set up a dvr controller and leaf? I tried to set them up but they  didn't work.

It would be a good idea to post your configs.  

Also,  GNS3 only comes with "As Is" support.  I don't know if DvR has ever been testing with GNS3.

on the controller :

Switch:1>en
Switch:1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#dvr controller 9

Switch1:1(config)#vlan create 200 type port-mstprstp 0
Switch1:1(config)#vlan i-sid 200 20200
Switch1:1(config)#interface vlan 200
Switch1:1(config)#dvr gw-ipv4 20.0.1.1
Switch1:1(config)#dvr enable
Switch1:1(config)#ip address 20.0.1.2 255.255.0.0

Switch1:1(config)#vlan create 202 type port-mstprstp 0
Switch1:1(config)#vlan i-sid 202 20202
Switch1:1(config)#interface vlan 202
Switch1:1(config)#dvr gw-ipv4 20.2.1.1
Switch1:1(config)#dvr enable
Switch1:1(config)#ip address 20.2.1.2 255.255.0.0
Switch1:1(config)#exit

Switch1:1(config)#ip vrf vrf501 vrfid 501
Switch1:1(config)#vlan create 501 type port-mstprstp 0
Switch1:1(config)#vlan i-sid 501 50501
Switch1:1(config)#interface Vlan 501
Switch1:1(config)#vrf vrf501
Switch1:1(config)#dvr gw-ipv4 50.1.1.1
Switch1:1(config)#dvr enable
Switch1:1(config)#ip address 50.1.1.2 255.255.0.0

Switch1:1(config)#router vrf vrf501
Switch1:1(router-vrf)#i-sid 55501 
Switch1:1(router-vrf)#ipvpn enable
Switch1:1(router-vrf)#exit
Switch1:1(config)#

on the leaf :

Switch3:1>en
Switch3:1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch3:1(config)#boot config flags dvr-leaf-mode
Switch3:1(config)#save config
Switch3:1(config)#reset

Switch3:1(config)#dvr Leaf 9

Switch3:1(config)#i-sid 20200 elan
Switch3:1(elan:20200)#c-vid 200 port 1/2
Switch3:1(config)#exit

I would start with something simple.  Do your controllers have the Premier License?

The leaf nodes don't need the PremLic, but your controllers 100% do.  

beyond that, we would need to see your configs. 

[Maryam]

No I don't have Premier License. I just do the configuration on gns3 for learning. I use the documentation for reference.
