Cisco identifies three rules that should be followed when configuring EIGRP over an NBMA cloud:
• EIGRP traffic should not exceed the CIR capacity of the VC.
• EIGRP's aggregated traffic over all the VCs should not exceed the access line speed of the interface.
• The bandwidth allocated to EIGRP on each VC must be the same in both directions.
If these rules are understood and followed, EIGRP works well over the WAN. If care is not taken in the configuration of the WAN, EIGRP can swamp the network.
