CORRECT TEXT
((EIGRP OSPF Redistribution Sim)
In this question you need to redistribute between OSPF and EIGRP such that 172.16.100.1 is
reachable from router R1.
R2 is an ASBR for EIGRP 100 and OSPF AREA 24
R3 is an ASBR for EIGRP 100 and OSPF AREA 34
NotE. There are TWO separate areas on TWO separate ASBRS thus you need to do redistribution
on R2 and R3
R1 is ONLY in EIGRP 100, and is THE ONLY router you can ping from. R4 has a loopback
interface that must be pinged from R1.
R4 is running OSPF and has redundant links to EIGRP network over R3 router.
NotE. You should ping from R1 to 172.16.100.1 network to make sure everything is working
correctly.
Answer: See explanation
Explanation:
First we need to find out 5 K-Values used for EIGRP (Bandwidth, Delay, Reliability, Load,
MTU) of the s0/0/0 interface (the interface of R2 connected to R4) for redistribution :
R2#show interface s0/0/0
Write down these 5 parameters, notice that we have to divide the Delay by 10 because its metric
unit is tens of microsecond. For example, we get Bandwidth=1544 Kbit, Delay=20000 us,
Reliability=255, Load=1, MTU=1500 bytes then we would redistribute as follows:
R2#config terminal
R2(config)#router ospf 1
R2(config-router)# redistribute eigrp 100 metric-type 1 subnets
R2(config-router)#exit
R2(config-router)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500
(Notice: In fact, these parameters are just used for reference and we can use other parameters
with no problem. Also, a candidate said that the simulator didn’t accept the Bandwidth of 1544; in
that case, we can use a lower value, like 128.)
If the delay is 20000us then we need to divide it by 10, that is 20000 / 10 = 2000)
For R3 we use the show interface fa0/0 to get 5 parameters too
R3#show interface fa0/0
For example we get Bandwidth=10000 Kbit, Delay=1000 us, Reliability=255, Load=1, MTU=1500
bytes
R3#config terminal
R3(config)#router ospf 1
R3(config-router)#redistribute eigrp 100 metric-type 1 subnets
R3(config)#exit
R3(config-router)#router eigrp 100
R3(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500
