l2tpv3 compatibility problem? one side of tunnel state is established, other side is Wt-SCCCN

[CSCO10936521]

Hello.

I am running into an issue with setting up a l2tpv3 tunnel between 2821 router 15.1(4)M9 and 3725 router 12.4(15)T7. The topology is straightforward. They are on the same LAN and the local interface used in pseudowire-class is just the lan interface itself. There's no authentication and every parameter is by it's default.

The tunnel remains down status:

R1#sh xc a
Legend: XC ST=Xconnect State, S1=Segment1 State, S2=Segment2 State
UP=Up, DN=Down, AD=Admin Down, IA=Inactive, NH=No Hardware
XC ST  Segment 1                         S1 Segment 2                         S2
------+---------------------------------+--+---------------------------------+--
DN     ac   Fa0/1(Ethernet)              UP l2tp 10.0.1.0:60                  DN

and "show vpdn tunnel all" reveals that on one end (3700) side,

":Tunnel state is established"

and yet on 2800 side,

"Tunnel state is Wt-SCCCN"

Checked configuration so many times and there's really nothing else to check because it was the simplest way. Any help would be greatly appreciated.

Thanks.

Never mind, found the workaround.

Hey CSCO10936521 , what was the workaround.

Having same issues here establishing an xc between 1811 (124-15.T1) and a 1921 (152-2.T1)

Thanks,
