I figured out that the syntax of DEFUN commands in FRR 3 is different from Quagga. I found this problem when i saw my old (Quagga based) code raise errors when copied in FRR!

For example, it seems that () has no meaning or different interpretation! As another example i think argvs are counted for all words in the command not only variables! am i right?

So i have 2 questions

1. Where can i find the differences of DEFUN in FRR?

2. A trouble!!! When i input the argvs in vtysh in a different order, I will take different argv values!!!!!!!

For example: i have in DEFUN:

"snmp-server group NAME <v1|v2c> {read WORD|write WORD|notify WORD|context WORD}"

Now, in vtysh, if the user enters:

Router# snmp-server group g1 v1 write view1 read view2

My DEFUN considers argv[5] as view1 and argv[7] as view2

and if user enters:

Router# snmp-server group g1 v1 read view2 write view1

 
My DEFUN considers argv[7] as view1 and argv[5] as view2

While in my DEFUN, i expect that snmp write view always to be (e.g.) argv[5]

Please help.

Thanks
