The correct answer is B. Configure the redistribution between EIGRP and MP-BGP. In Cisco ACI, MP-BGP (Multiprotocol BGP) is used to distribute external routes learned via L3Outs across the fabric. Since the EIGRP routes are only present on the border leaf, it indicates that the redistribution of EIGRP into MP-BGP is missing. - The border leaf learns EIGRP…
Question
Refer to the exhibit. An engineer configured an L3Out to exchange routes with the rest of the network, but the EIGRP routes are present only on the border leaf. As a result, the servers from Leaf1 fail to communicate with the external networks. The configuration of the L3Out was confirmed. Which action in the initial fabric setup must be taken to accomplish these goals?
Exhibit
Options
- AChange the ISIS metric for redistributed routes to 32.
- BConfigure the redistribution between EIGRP and MP-BGP.
- CDefine the border leaf as BGP Route Reflector.
- DDefine spines as BGP Route Reflector.

Explanation
In Cisco ACI, MP-BGP (Multiprotocol BGP) is used to distribute external routes learned via L3Outs across the fabric. Since the EIGRP routes are only present on the border leaf, it indicates that the redistribution of EIGRP into MP-BGP is missing. - The border leaf learns EIGRP routes from CORE but does not propagate them to other fabric - The leaf switches use MP-BGP to exchange routes, so without proper redistribution, EIGRP routes remain isolated on the border leaf. 2. The solution: - Redistribute EIGRP into MP-BGP so that the routes can be advertised across the fabric to other leaf switches. - Configure route redistribution under the L3Out EIGRP settings to ensure external routes propagate within ACI.
