we have point to point metro ethernet link terminating on 7204VXR router.On this point to point link we are configuring GRE over ipsec. Problem is when the traffic exceeding 8mbps we started getting packet drops.
from the cisco documentation it seems the tunnle bandwidth is by default 8mbps and there is parameter like Inherit/receive but those actullay not change the tunnel interface bandwidth.If we just give tunnle bandwidth with bandwidth mentioned it allows me to give option of 100mbps but again the tunnle interface bandwidth remians 8mbpos only and probabaly that 100mbps is useful only for routing decisions.
i am using advance security 12.4.15T12 image.
can anyone please confirm weather this is a limitation or any other way to go beyond 8mbps for the tunnle interface (7204VXR-NPEG1 processor)
By default Tunnel bandwidth is set to 8mb. I don't remember the exact command but it should be in the vicinity of "tunnel bandwidth transmit " and "tunnel bandwidth receive ".
You can go beyond 8mbps. It all depends on the IOS Feature Set. If I'm not mistaken Advanced IP Services feature set will enable the "tunnel bandwidth" command.
