The exhibit shows R1 topology table to reach 192.168.1.0/24 network.
Which route(s) will be installed in routing table of R1 to reach network 192.168.1.0/24 after
configuring R1 with the following command?
Router(config-router)# variance 2
A.
R2 only
B.
R2 and R3
C.
R2 and R4
D.
R2, R3 and R4
Explanation:
EIGRP will only use equal-cost load-balancing feature even when the variance command is
used. However, if you use both the traffic-share min command and variance command, even
though traffic is sent over the minimum-cost path only, all feasible routes get installed into
the routing table, which decreases the convergence times
without the exhibit i would have to guess….
variance 2 is not enough to cause the AD of the feasible successor to be useful against the FD of the successor. therefor only the Successor is used EVEN when variance is 2. If variance is set higher…..10 say….then even if a Feasible Successor route SUCKS (ie.10times slower then the Successor’s route)
…it will STILL be un-equal cost load balanced that sucky route.
best is to limit variance to Feasible Successors that MAKE SENSE.
