Refer to the exhibit.
Which two corrective actions could you take if EIGRP routes from R2 fail to reach R1? (Choose
two.)
A.
Configure R2 to use a VRF to send routes to R1.
B.
Configure the autonomous system in the EIGRP configuration of R1.
C.
Correct the network statement on R2.
D.
Add the interface on R1 that is connected to R2 into a VRF.
In this question we are running VRF Lite on R1. VRF Lite is also knows as “VRF without running MPLS”. This is an example of how to configure VRF Lite with EIGRP:
ip vrf FIRST
rd 1:1
ip vrf SECOND
rd 1:2
router eigrp 1
no auto-summary
address-family ipv4 vrf FIRST
network 10.1.1.1 0.0.0.0
no auto-summary
autonomous-system 200
exit-address-family
address-family ipv4 vrf SECOND
network 10.1.2.1 0.0.0.0
no auto-summary
autonomous-system 100
exit- address-family
interface FastEthernet0/0
ip vrf forwarding FIRST
ip address 10.1.1.1 255.255.255.0
interface FastEthernet0/1
ip vrf forwarding SECOND
ip address 10.1.2.1 255.255.255.0
The above example creates two VRFs (named “FIRST” and “SECOND”). VRF “FIRST” runs on EIGRP AS 200 while VRF “SECOND” runs on EIGRP AS 100. After that we have to add interfaces to the appropriate VRFs. From this example, back to our question we can see that R1 is missing the “autonomous-system . ..” command under “address-family ipv4 vrf R2. And R1 needs an interface configured under that VRF.
NotE. R2 does not run VRF at all! Usually R2 resides on customer side.
so, answer – BD
