Hi All

Can you somebody help me in understanding whey GRE tunnel Cisco WS-SUP720-3BXL , with two GRE tunnel configured will spike the cpur to 99% when the traffic goes beyond 30mbps.


According to documentation, the GRE is hardware accelerated, please note that the two tunnel interface has two different source interface ( SVI source ip address  )
