and i can see that :
Switch1.1 is up, line protocol is up < all traffic goes here Interface is unnumbered. Using address of Loopback0 (172.31.1.2) Broadcast address is 255.255.255.255 MTU is 4470 bytes Helper address is not set Directed broadcast forwarding is disabled Multicast reserved groups joined: 224.0.0.5 224.0.0.6 Outgoing access list is not set Inbound access list is not set Proxy ARP is enabled Local Proxy ARP is disabled Security level is default Split horizon is disabled ICMP redirects are always sent ICMP unreachables are never sent ICMP mask replies are never sent IP fast switching is enabled IP fast switching on the same interface is enabled IP Flow switching is disabled IP CEF switching is disabled <-- i guess thats it IP Feature Fast switching turbo vector IP Null turbo vector IP multicast fast switching is disabled
which is weird cos i see:
RPM1#sh run | in ip cef ip cef
What could be breaing my CEF, so it punts everything to CPU ?
