I have a small problem with one of my INE labs i'm doing.. doing MPLS TE with Targeted LDP Adjacencies, I'm doing it with there workbook on a real lab, Section 5.7, the problem I'm facing is the when the TE tunnel is connected from R2 (PE) to R6 (P) and Xr1 (PE) to R3 (P) respectively. When the TE tunnel is conected from R2 to R6, R2 learnes the loopback of R6 and R6 routes via the Tunnel with ISIS even though ISIS is not enabled on the interface nor showing an adjancencie with R6.

This is causing the end to end connectivity to fail. I have looked at the solution but cant see anything wrong with my config.
Any suggestion?
