I have a 877 cisco router.
I want to put 2 ip addresses on this router.
This addresses are in different networks and differents vlan untagged.
I want to use port fastethernet0 and fastethernet1 to connect the router to another switch router.
My switch did vlan by port.
I use switchport access for the first vlan and I can put the IP on the FE0.
But when I try to put the second vlan and second IP I can't add a new vlan because the router is blocked for 2 vlan and first vlan is not deletable.
When I try to put directly the ip to interface I issue an error message.
How can I put 2 ip from diffrents network on my router (on two differents physical ports) in order to communicate with my other switch router?
