I have this setup configured where an IPSEC tunnel is established between 10.15.10.2 and 10.16.70.2 . Now I want pass traffic through the same tunnel from two more diffrent network ip's. So for that, i have created 3 VLAN interfaces so that will make Feth1 as trunk mode but i was not able to use switchport command on that interface. What other solution I can look for?
