I have an IPsec tunnel between Site A and Site B.
Site A also has a GRE tunnel to Site C.
Site A ---- IPsec---- Site B
I need to measure the bandwidth being used (an available) between both connections.
So, I need to measure the bandwidth via the IPsec tunnel and the bandwitdh via GRE tunnel for some routing policies.
My question is, what's the recommended way to do this?
As Jon mentioend from Router you can get some info with these commands
sh int summary ( for GRE Tunnel )
sh crypto ipsec sa ( IPSEC )
If you have monitoring tool then you can get the amount of data transfered and traffic type.
We did a pilot with solarwinds NPM and Netflow Module ( www.solarwinds.com ) and got the details.
Hope this input helps.
"sh crypto ipsec sa" should show you the amount of packets sent and received on the IPSEC tunnel. Not sure about GRE and whether you can see packets in/out on the tunnel interface itself. Have you tried "sh interface tunnel" ?
I'm assuming the problem is because both the IPSEC and GRE go via the same interface on the router ?
Use FTP to transfer a very large file (100+ MB) messure traffic.
