Set minimum-links 2 to AMS-IX LACP
Closed, ResolvedPublic

Description

[edit interfaces ae2 aggregated-ether-options]
-    minimum-links 1;
+    minimum-links 2;

We're above 10G of traffic so if one (soon 2) link goes down, it will saturate the other one, paging people, until someone disable it.

Better to take the whole bundle down and let BGP balance traffic to the transit links.

No mention of the change to cause any flap.

Thanks! This will also help in case the wrong cable gets bumped into during the new link provisioning.
