On a 1841 - Backup interface for vlan inerface - tunnel interface
On a Cisco 1841 router I have an Interface vlan configured. Also I have f0/0/1 interface defined as switchport access with the same vlan. Is it possible to now define a tunnel interface and have it include the following - backup interface vlan xx ?
Interface vlan 55
ip addresss 10.0.0.1 /24
ip address 10.0.1.100 /24
switchport access vlan 55
backup interface vlan55
ip address 10.0.2.33/24
Is this configuration valid on a 1841 with these interfaces ? Can the "backup interface " be used in this situation ?

Thanks for the answer. You are correct , the interface f0/0/1 is switchport access and no ip address. I simply did not write it correctly in the question.
I did not see in Cisco examples the use of 'backup interface" in this kind of situations. Mostly just for dialer interface. So i understand that this should work. There is in fact only one interface in the vlan.
