Q1) Use specific wildcard masks on R2 and R3.
: ex)
router eigrp 90
network 172.30.1.0 0.0.0.0
Q2) EIGRP should be configured in such a way that it does not operate like a classful routing protocol.
: router eigrp 90
no auto
Q3) How to advertize default route which is 192.168.1.0/24 in BB? Don't use static and redistribute static.
1. ip route xxxx xxxx xxxx
2. redistribute
3. ip default-network xxxx (IP address must be classful network)
:BB>
conf t
ip defalt-network 192.168.1.0
Q4) EIGRP shold not form neighbor relationships on any interface where other EIGRP routers do not exist.
BB>
conf t
router eigrp 90
passive-interface default (It turns off sending hello packet to every network)
no passive-interface s0/0 (turn on sending hello packet on this interface)
no passive-interface s0/1
R2>
conf t
router eigrp 90
passive-interface f0/0
Q5) Advertize 172.30.0.0 - 172.30.7.255 into a single netowrk in BB
:BB>
int s0/0
ip summary-address eigrp 90 172.30.0.0 255.255.248.0
int s0/1
ip summary-address eigrp 90 172.30.0.0 255.255.248.0
Q6) BB router should perform unequal load balancing to reach the 10.1.2.0/24 network
(By default, EIGRP do the load balancing. However, both load must be exectly same metrics. = variance of one)
variance of two is that two times of metric of Feasible distance can be load balanced.
variance of three is that three times of '' '' '')
:BB>
conf t
router eigrp 90
variance 2
