Our new ip uplink is using QiNQ to get our vlans sent to our head router. This brings our C-vlans mtu down to 1572 (upstream s-vlan interface is 1576, 1580 on bridge/eth)
are we fragmenting with this current l2 MTU setup?
- should i make an mtu change on the l2 MTU?
- should i also tell the upstream ISP switch to accept a new mtu?
Please let me know if i should change MTUs to keep from fragmenting. our entire network is ethernet and at 1500 L3 mtu
