Hi,
You are right that the bandwidth command doesn't change the speed of the
link. But EIGRP used the configured bandwidth under te interface to
determine the maximum allowed bandwidth for routing updates.
EIGRP will use up to 50 percent of the bandwidth of a link, as defined by
the bandwidth interface configuration command. This command may be used if
some other fraction of the bandwidth is desired.
The feature below can be usefull to. If you've configured the interface with
a very low administrative bandwidth (for routing optimization e.g.) you can
configure that EIGRP may use 200% for routing updates.
--> Note that values greater than 100 percent may be configured. The
configuration option may be useful if the bandwidth is set artificially low
for other reasons. <--

Ryan,
Method 2 as you described will not work. Putting the bandwidth command
directly onto the interface does not effect the speed of the link. The
bandwidth command is just a reference used for metric calculation and MQC
reference.

Subject: EIGRP routing protocol traffic in FastEthernet Interface
Hi Group,
One easy question but I want to double confirm.
If I only want to allow EIGRP Routing Protocol 10Mbps (Max) traffic on
Fastethernet interface, can I accomplis by the following methods?
Method 1:
=========
interface f0/0
ip bandwidth-percent eigrp 1 10
Method 2:
========
interface f0/0
bandwidth 20000
! Because it use 50% as eigrp routing protocol, by default.
Any more method ?
Thanks a lot!
Ryan
