Junos OS

 Hi every body.

 I come from Cisco background but have been placed in Juniper role at my current job.

I have a a question:

Let say i want to create gre tunnel.

set chassis fpc 1 pic 1 tunnel-service

Next I want to create a gre interface,

set gr-1/1/x unit 0 tunnel source 1.1.1.1

set gr-1/1/x unit 0 tunnel destination 2.2.2.2

My question is :

 What are some values  can i use for x above?

Thanks and have a nice weekend!!

The last number will be zero.

You can confirm this after you commit the creation of the gre interfaces.  You will see the new interface listed in

show interfaces terse | match gr

You then can figure mulitple units on this interface if you need to have more than one gre tunnel on the device.

Thanks Sir!!
