[alcatel-nsp] 7750SR and Juniper MX480 VPLS full mesh interopt

Hi All,

Got question regarding the following VPLS setup:

7750SR(A) <--------------->MX480(A)<---------------->MX480(B)<----------------->7750SR(A)
                    mesh-sdp                                                     mesh-sdp

- All PE suppose to be fully mesh in a triangular formation. 
- 7750SR VPLS service configured using  mesh sdp with the 2 Juniper MX480.
- Server at MX480(A), while client PC at 7750SR.

Question is, when client PC wish to establish connection with server, will there be a loop or mac-move trigger on 7750SR? Will the mesh-mesh violation between MX480(B) and 7750SR take place hence deny any traffic traverse via that LSP tunnel and instead traffic will proceed thru MX480(A)? 

Appreciate if anyone could help and comment.... Thanks.
