Final answer:
CoA is used to restrict or allow traffic based on specific conditions in routing, while C-Coa is a more advanced form of CoA that allows for more granular control over traffic.
Step-by-step explanation:
CoA stands for Control of Admission.
C-Coa stands for Conditional Control of Admission.
In routing, CoA is used to restrict or allow traffic based on specific conditions, such as source IP address, destination IP address, or traffic type. On the other hand, C-Coa is a more advanced form of CoA that allows for more granular control over traffic, including conditions based on multiple factors or complex logical expressions.
