cef routing support for GRE over IPSec tunnels on Cisco 7301 router
I have a WAN setup using GRE over IPSec to enable OSPF routing updates. The OSPF is working fine and traffic is flowing across the network through the GRE tunnels, however rather than using CEF to switch the packets through the router it is punting the traffic down to the route processor for routing. If the GRE over IPSEC tunnel is not used traffic is processed using CEF.
This only happens on one router on one side of the WAN, and only for incoming traffic on the outside interface. The router in question is a Cisco 7301 running IOS version 12.4. CEF is enabled globally and on the interface in question. Does anyone know if CEF switching is unsupported using GRE over IPSec on this router and IOS?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
