 The supervision and maintenance of BEIGRP
59.2.1 Activating BEIGRP Protocol
In order to create a BEIGRP process, it is required to execute the following commands:
Command Purpose
router beigrp
as-number Add a BEIGRP process under global configuration mode
network
network-number
network-mask
Add addresses to this BEIGRP process under router configuration
mode
After finishing the above configuration, BEIGRP will start to run on all interfaces belonging to this address,
discoveres new neighbours through “Hello” and carryes out initial routing interaction through “update”.
59.2.2 Configuring the Sharable Percentage of Bandwidth
Under default circumstances, BEIGRP can occupy 50% of the bandwidth at most. You may wish to change
this default value in order to guarantee the normal interaction of other data, or wishes to adjust the actually
usable bandwidth of BEIGRP through the command when the interface is configured with a bandwidth not fit
for actual situation. Under these conditions, you can use the following commands under interface
configuration mode:
Command Purpose
ip beigrp bandwidth-percent
percent Configure the maximum percentage of BEIGRP
messages’ occupation of the bandwidth
59.2.3 Adjusting the Arithmetic Coefficient of BEIGRP Composite
Distance
Under certain situations, the arithmetic co-efficient of BEIGRP composite distance may need to be adjusted,
and finally influences the routing policy of the router. Although the default arithmetic co-efficient of BEIGRP
can satisfy most networks, but it may still need to be adjusted under some particular conditions. But this adjust
may bring great change to the whole network, so it must be performed by the most experienced engineers.
Use the following command under router configuration mode:
Command Purpose
metric weights
k1 k2 k3 k4 k5 Adjust the arithmetic co-efficient of BEIGRP composite distance.
59.2.4 Using “Offset” to Adjust the Composite Distance of the Router
We use offset list to purposely add all incoming and outcoming routes according to the requirement, or the
composite distance of certain routes meeting the requirements. The aim of this approach is to finally influence
the routing result of the router, and meets our expected result. During the process of configuration, the user
can designate access list or application interface in the offset list selectively and according to your requirements,
in order to more clearly notify which routes to carry out operations to increase offset. Looking at the following
command:
