Re: JunOS not identifying duplicate addresses on different interfaces of same device
2 weeks ago
At some point there was an attempt to add such check, but then it was reverted back to the original JUNOS day 1 behavior.
This is to support scenarios with 1:1 line side protection. In these scenarios customers configure identical addresses on different physical interfaces. One physical interface is active at a time (controlled by the transport equipment).
If someone needs to enforce additional checks, we have a commit script option.
