would you please advise about the attached setup. is it going to work or we need to change the design.
we have below configuration:
span tree mode on sw1 is MST.
the two Peplink devices are configured in HA mode and connected to each other by back to back cable.
we have two vlans on SW1 (VLAN 107, and Vlan 103), each one with four ports, two of them which connected to the firewall cluster
are in access mode, while the other two ports which connected to Peplink master and slave boxes are in
trunk mode.
could you please advise about this setup, if it will work well or not.
Dear kv_Chen,
With this setup, only one trunk connection is working with us, and the other one is getting blocked.
Can you advice how to resolve the issue.
the two trunks which is connected to the master and coming from two different vlans (103, and 107), we have one of them up and the second is getting blocked. i.e. we can ping the IP address of peplink vlan 103 but not able to ping 107.
for span tree, the sw1 is cisco switch and using mst for span tree.
actually it is the customer requirement to have one trunk per vlan, so we can’t remove the trunk.
For the back to back cable, we may remove it later as we are planning to connect a third vlan. it will be the native vlan and vrrp messages can go through it.
is there any issue in case we have multiple trunk between the Cisco switch and the peplink devices.
