$ ip -d link show tun10
11: tun10@NONE: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1476 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 1000

Now change the tunnels remote IP address:
`set interfaces tunnel tun10 remote-ip 172.18.254.203`
```
$ ip -d link show tun10
11: tun10@NONE: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1476 qdisc pfifo_fast state UNKNOWN mode DEFAULT group default qlen 1000
link/ether 1e:79:b5:00:6b:09 brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 68 maxmtu 0
gretap remote 172.18.254.201 local 172.18.254.202 ttl inherit addrgenmode none numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535
```
The problem is b/c the `GRETapIf` class states:
```
# GreTap also called GRE Bridge
class GRETapIf(_Tunnel):
...
def change_options(self):
pass
```
Thus the change is simply skipped. The reason is - the OS (Linux) Kernel does not support changing gretap tunnel interfaces parameters at all. A workaround will be to simply create and destroy the tunnel automatically.
