Hi
We have an IPSec over GRE tunnel from Site A to Site Z, travelling through a big cloud from A->B- --- to --- Y->SiteZ.
The protected networks in SiteA are having a lot of latency accessing the intended servers in SiteZ through the encryption path.
The tunnel Util shows 255/255 both Tx and Rx.
But there are no output drops whatsoever.
My question of concern is,
<1>On what basis does this utilization get calculated ?
<2>Also, the Bandwidth statement on the tunnel interface is only for the routing protocol as I understand it.
Thanks in advance :0)
