Hi
For first question , not all.
I hope xe-1/3/2.1 is primary, gr-2/3/0.2 is second and gr-1/1/0.3 is thirth.
For second question, both tunnel source IP are not on xe-1/3/2.1.
Their source IP are different interface what connect to global upstream provider.
BTW, xe-1/3/2.1 is connected to other router directly via submarine cable as point to point.
Thanks for your reply.
