I am having a problem when i connect a link to Cisco 6500. CPU starts jump up 100% (both process and interrupt) always. The link is mpls and ospf enable. the router connect other routers via the link which then saparate by sub-interface. "show process cpu sort" shows "LFDP Input Proc" alone is consumpting more CPU then other (aroud 20% to 30%). Other process seemed normal.
