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?

    % Password expiration warning.
    -----------------------------------------------------------------------
    
    Cisco Router and Security Device Manager (SDM) is installed on this device and
    it provides the default username "cisco" for  one-time use. If you have already
    used the username "cisco" to login to the router and your IOS image supports the
    "one-time" user option, then this username has already expired. You will not be
    able to login to the router with this username after you exit this session.
    
    It is strongly suggested that you create a new username with a privilege level
    of 15 using the following command.
    
    username <myuser> privilege 15 secret 0 <mypassword>
    
    Replace <myuser> and <mypassword> with the username and password you want to
    use.

    Cisco Router and Security Device Manager (SDM) is installed on this device.
    This feature requires the one-time use of the username "cisco"
    with the password "cisco". The default username and password have a privilege level of 15.
    
    Please change these publicly known initial credentials using SDM or the IOS CLI.
    Here are the Cisco IOS commands.
    
    username <myuser>  privilege 15 secret 0 <mypassword>
    no username cisco
    
    Replace <myuser> and <mypassword> with the username and password you want to use.
    
    For more information about SDM please follow the instructions in the QUICK START
    GUIDE for your router or go to http://www.cisco.com/go/sdm
