When configuring EIGRP to run across a 56 Kbps serial PPP link, what command do you
need to put under the serial interface ensure proper convergence of EIGRP routes?
A.
bandwidth 56
B.
bandwidth 56000
C.
ip bandwidth-percent eigrp 1 56
D.
ip bandwidth-percent eigrp 1 56000
Explanation:
When configuring serial links using EIGRP it is important to configure the bandwidth setting
on the interface. If the bandwidth setting is not changed for these interfaces EIGRP assumes
the default bandwidth on the link instead of the true bandwidth. If the link is slower, the router
may not be able to converge, routing updates might become lost, or suboptimal path
selection may result. Router(config-if)#bandwidth kilobits The value, kilobits, indicates the
intended bandwidth in kilobits per second. For generic serial interfaces, such as PPP or
HDLC, set the bandwidth to the line speed.
