Hello, we have the same issue between 2911 and 3825 with l2tpv3. Dynamic tunnel didn't become up, but use manual tunnel and it's working.

i.e.

R1:

pseudowire-class pwclass

encapsulation l2tpv3

protocol none

ip local interface Loopback0

!

interface GigabitEthernet0/1.316

encapsulation dot1Q 316

no cdp enable

xconnect x.x.x.x 316 encapsulation l2tpv3 manual pw-class pwclass 

  l2tp id 2001 1002 

  l2tp cookie local 4 201

  l2tp cookie remote 4 102

end

R2:

interface GigabitEthernet0/1.500

encapsulation dot1Q 500

no cdp enable

xconnect y.y.y.y 316 encapsulation l2tpv3 manual pw-class pwclass 

  l2tp id 1002 2001

  l2tp cookie local 4 102

  l2tp cookie remote 4 201

end

To configure L2tpv3 on your c2911 you need the feature datak9 to be active.

verify by doing the # show license command. If showing "not Active" try this link to learn more about enabling the evaluation.
