A hybrid routing protocol that fits the description you're looking for is the Enhanced Interior Gateway Routing Protocol (EIGRP).

Key Features of EIGRP:

1. Hybrid Protocol:

   • EIGRP combines the features of both distance-vector and link-state routing protocols, making it a hybrid protocol. This allows it to achieve fast convergence and efficient routing.

2. Support for Multiple Protocols:

   • Initially designed for IP, EIGRP also supports other protocols like IPX and AppleTalk through the use of Protocol Dependent Modules (PDMs). This makes it versatile in supporting multiple network layer protocols.

3. Efficient Use of Bandwidth:

   • EIGRP limits unnecessary network traffic by using events rather than periodic updates. Only changes in the routing table are propagated, rather than the whole table, reducing bandwidth usage.

4. Rapid Convergence:

   • EIGRP uses Diffusing Update Algorithm (DUAL) to ensure loop-free and rapid convergence, quickly adapting to network changes.

5. Scalability:

   • It is highly scalable, making it suitable for both small and large network environments. It supports variable-length subnet masking (VLSM) and classless inter-domain routing (CIDR).

6. Support for Auto-Summarization:

   • While EIGRP supports auto-summarization, it can also be manually manipulated to control the summarized routes, leading to more efficient route management.

EIGRP is commonly used within autonomous systems and is known for its balance between ease of use, efficiency, and performance. If you need to achieve the benefits of multiple protocol support and efficient network traffic management, EIGRP is a strong contender.
