Hi Anil, There appears to be a conflict here. Is it Secondary addresses ( ie: 2 ip addresses on the same physical port) or subinterfaces.
If you need secondary addressing use something like this conf t int fas0/0 ip address 10.128.10.1 255.255.255.0 ip address 172.16.16.1 255.255.255.0 secondary If you want subinterfaces you will need to set the encapsulation of each subinterface: conf t int fastethernet 0/0.1 encapsulation Hope this helps matters Regards Richard Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=28048&t=28027 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
