I am new to traffic shaping and traffic policing, so please bear with me. I have attached a diagram of the network configuration to serve as a visual exhibit. I have also pasted the configuration of the Cisco 1941 at the DR site. I have anonymized all information to protect the innocent.
I have two Cisco 1941 routers that provide a secure IPsec VPN tunnel between my production and DR sites. I am replicating snapshots from my production SAN to the DR SAN located at the DR site. I am alotted 6Mbps on the Internet circuit at the DR site by my ISP. However, the ISP does not have anything in place to throttle my bandwidth. When replication takes place, the replication traffic is peaking at 75Mbps. This is obviously a problem because the ISP is charging us for the overage. I have tried to implement simple traffic shaping and traffic policing in an attempt to limit the bandwidth used by the replication traffic, but I have been unsuccessful up to this point. Can somebody please provide some guidance here? What is a simple way of limiting the bandwidth on the router located at the DR site? You will see in the config below my unsuccessful attempt at traffic policing, which I implemented after my unsuccessful attempt at traffic shaping.
if I understood the description right, you replicate data from production data to DR site and have policing applied inbound on DR site router.
Applying it inbound in DR site will not help as it will try to drop any traffic beyond the configured rate inbound. Instead try the below,
1. Configure shaping with rate @ 6 Mbps.
2. Apply it outbound in production router.
This way, data replicated from production site while reaching the production router will be shaped/buffered and maintained @ 6 Mbps rate. Using shaping will help you not to drop any packet (like policing). Instead will buffer and send across.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
