Issue with Distributed Trunking and pings
Recently we've configured 4 HP switches which are using Distributed trunking. See picture
So the problem is this.
Rack 4 has 2 switches (Left on the picture). One of these switches is the root bridge for the STP instance.
Rack 6 has also 2 switches (Right on the picture). One of these switches is the root bridge for this STP instance.
What is failing:
From 10.0.0.13 I am unable to ping 10.0.0.17 and vice versa. I am however able to ping the directly connected switches from 10.0.0.13 as well as from 10.0.0.17
What is going on?
