EIGRP has been configured to operate over Frame Relay multipoint connections. What should the bandwidth command be set to?
A.
the CIR rate of the lowest speed connection multiplied by the number of circuits
B.
the CIR rate of the lowest speed connection
C.
the CIR rate of the highest speed connection
D.
the sum of all the CIRs divided by the number of connections
Answer: A
Explanation
If the multipoint network has different speeds allocated to the VCs, take the lowest CIR and simply multiply it by the number of circuits. This is because in Frame-relay all neighbors share the bandwidth equally, regardless of the actual CIR of each individual PVC, so we have to get the lowest speed CIR rate and multiply it by the number of circuits. This result will be applied on the main interface (or multipoint connection interface).
