VPN used loopback counts +1 after reload

Hi *,

 

We have a Cisco 886 router with an IOS 15.X. 

The VPN Tunnel is built on a loopback (lo10000) interface of the VPN tunnel.
At the same time the loopback interface is the Source interface for TACACS, Logging & SNMP.

Everything works beautifully. 

However, if you make a reload, the tunnel uses the next free loopback interface -> for example loopback interface 10001 ...  with every reload the Loopback Adress is incremented by one number. What the rest of the configuration (TACACS, SNMP, etc.) confuses, and therefore no longer works . 

Does anyone have an idea what the problem is?

Thanks in advance!
