Routing

Hi everyone.

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:

Junos: 14.1R1.10

Much appreciated!!

Hi,

Try "disable-4byte-as".

https://www.juniper.net/documentation/us/en/software/junos/cli-reference/topics/ref/statement/disable-4byte-as.html

Note that this command is "hidden", so, it will not show up when you press ? to see available commands, but it is there -

[edit]
root@RR# show protocols bgp |display set | match 4byte 
set protocols bgp group ibgp disable-4byte-as
