I've been trying to figure out how to setup a GRE tunnel between an ALU 7750SR and a 3rd party vendor. I think it's balking at the VC-ID in the SDP but i'm hoping someone has experience getting a GRE tunnel to come up in a multi-vendor environment with ALU.

Here's the requested syntax:

sdp 9999 create
far-end 1.1.1.1 
path-mtu 1500 
keep-alive 
exit

ies 9998 customer 1 create 
 interface "PACKET_DESIGN" create 
 address 10.128.105.6/30 
 spoke-sdp 9999:1 create 
 no shutdown 
 exit 
no shutdown
