We have third party firewall cluster. We are configuring Azure Express route in our infrastructure. On Microsoft side, there are 2 vlans for Microsoft peering and one for private peering. They also have primary and secondary connection for each peering so our firewall ports are configured as trunk. For each peering I need to have same VLAN tagging but different IP for primary and secondary connection. So one fiber optic cable will be bridged to FW1 and one for second FW2. One cable carries 2 vlans for primary connection, second cable carries same vlans but for secondary connection.
I need to configure Cisco switch ports as trunk and allow same vlans but they shouldn't intervene each other. How can I achieve this? Please suggest me solution.
