Title: subinterfaces

You need to reboot the router to get rid of a sub interface. Maybe Secondary IP addresses would be a solution for what you want to do.   Also, the router is stating that to route between ethernet Sub interfaces you need ISL or dot q because it assumes you will be routing between Vlans. Why? Because if you actually had a physically seperate network to route to you would put it on another interface not the same sub interface of a physical segment. The interface assumes since you are trying to bring in 2 networks on the same interface that you are using Vlans.         ----- Original Message ----- From: Nova Rich To: '[EMAIL PROTECTED]' Sent: Thursday, August 31, 2000 7:53 PM Subject: subinterfaces hey guys, I was wondering how to apply subinterfaces. I have 1 ether port on my router (1600) and need 2 links to the switch. One for public IP and the other for private IP. I type in "int e0.1", then "ip add x.x.x.x mask" but I get this instead, "Configuring IP routing on a LAN subinterface is only allowed if that subinterface is already configured as part of an IEEE 802.10 or ISL vLAN." I don't know why this won't work and further more I can't seem to remove the subinterface. I type in (no int e0.1) but I still see the interface when I do a (sh ip in b). "Ethernet0.1              unassigned      YES manual deleted               down" It's marked as deleted but how do I get rid of it entirely? How do I configure subinterfaces and how do I remove them?
