I am trying to set up a lab between two BGP speakers , such that one only support AS ( 2 bytes) and while the other can support AS-4 bytes format.
Unfortunately, both of my vMX supports AS-4 bytes format.
Is there any command that we can use to force to operate in AS-2 bytes format and announces AS-2 bytes compatibility in BGP open message?
My vMX is running:
Just checking - you really have a VMX instance that is 10 yrs old? JUNOS supports both AS-2 and AS-4 - when presented with a 2byte AS, it maps to prefix the leading 2 bytes with 0s when dealing with a peer that does AS-2. What are you seeing?
