Re: Ex2300 switch irb interface pinging access vlan not reachable
I see you configured VLANs from 100 to 150, however, there is only one IRB configured under VLAN 10. If this switch is working as the gateway for all VLANs, you need to configured an IRB for each Vlan with its corresponding subnet so the switch can perform intervlan routing.
If your scenario is different kindly share more details.
If this clears your concerns please mark as solved
