HI , I am planning to link up 2 3845 routers with 1 3845 router at my data center. Will the data throughput affected?

IS there any site have similar setup for reference?

Just do not expect to be able to use a gigabit link at wire speed. Use L3 switches for that.

Often the data throughput is more dependent on the amount of traffic being forwarded more so than the number of links. In other words, a 3845 has a certain level of data forwarding that it can support, doesn't matter as much number of peer/connecting routers, more so traffic volume that will be passed though it. Of course, everything else being equal, more links/peers might increase traffic load.

A 3845 is recommended for T3s (single one), but they also seem to be able to forward up to about 100 Mbps (duplex).
