I am trying to configur a cisco 857 router and experienced problems with the config of the interface fastethernet ip address.
Can someone please help-me?
"R2(config)#int fastether0
R2(config-if)#ip address 192.168.1.251 255.255.255.0
% IP addresses may not be configured on L2 links.
R2(config-if)#"
Thanks in advance

Hi,
I suppose you connect your internal machine on fa0 then do this:
int vlan 1
ip add 192.168.1.251 255.255.255.0

Hi,
Because this is a Layer 2 interface(switchport) not a Layer 3 interface and you can't assign an IP to a L2 interface.
