How to COMPLETELY delete vlans in cisco router(s)?

by admin on December 14, 2009

I’m working on a cisco 3825 router and deleted a vlan using the "no" command. After saving the config and typing "sh startup" the vlan is gone, but when I put in the "sh interface description" command it still shows the vlan and says that it is deleted. Is there a way that I can get rid of it completely? Some sort of counter to clear or something?
