I don't know where this is documented but anything above 5Gbps is considered
to have 10Gbps:

+++++++++++++++++++++++++++++++++++++++++++
Router(config-if)#band 5000000                     
Router(config-if)#do sh ip eigrp topology 6.0.0.0/8
IP-EIGRP (AS 6): Topology entry for 6.0.0.0/8
  State is Passive, Query origin flag is 1, 1 Successor(s), FD is 128256
  Routing Descriptor Blocks:
  0.0.0.0 (Null0), from 0.0.0.0, Send flag is 0x0
      Composite metric is (128512/0), Route is Internal
      Vector metric:
        Minimum bandwidth is 5000000 Kbit
        Total delay is 5000 microseconds
        Reliability is 255/255
        Load is 1/255
        Minimum MTU is 1514
        Hop count is 0
Router(config-if)#band 5000001

Subject: EIGRP Metric Calculation

Hello All, could someone please confirm what the metric of a locally
configured summary route would be based on. For eg: Say if I have a loopback
interface in the x.x.3.0/24 range and I am also receiving routes via eigrp
x.x.0.0 /24, x.x.1.0/24, x.x.2.0/24 I see that the metric is a bit
different. Won't the eigrp metric be calculated based on the loopback
interface since it should have the lowest metric as its a local interface.
So if the bandwidth on the loopback interface is 8000000 and the delay is
configured on the loopback interface as 5 how come when doing a show ip
eigrp topology for  1.1.0.0 255.255.252.0 route I see that the minimum
bandwidth is 10000000. Its completely changing the metric and I can't seem
to tell why its seeing the bandwidth as 10000000. Thanks for your help.
