I read that the ip bandwidth-percent eigrp [as] [percent] command should be issued on point-to-point interfaces to limit the amount of EIGRP traffic.
So the bandwidth command will only be used for route metric calculations?
How about the same command on NBMA networks?
the ip bandwidth-percent eigrp command instructs EIGRP on how to send its traffic.
Without it EIGRP should use up to 50% of the bandwidth value.
The command is useful in NBMA environments where a low bandwidth value is provided in some scenarios to every subinterface. Actually the command accepts even a value greater then 100% for this reason.
On point-to-point links I don't see a real need for this.
Hope to help
