As the lead network engineer responsible for designing a complex global network infrastructure for a multinational corporation, you need to choose a routing protocol that balances efficient routing updates and scalability. The company operates in diverse geographical locations and requires seamless communication between its branches.

To make the best choice, let's evaluate the available routing protocols:

1. RIP (Routing Information Protocol): RIP is a distance-vector routing protocol that uses hop count as the metric. While it is simple to configure and deploy, it may not be the best choice for a complex global network due to its limited scalability and slow convergence time.

2. EIGRP (Enhanced Interior Gateway Routing Protocol): EIGRP is a Cisco proprietary routing protocol that combines the best features of both distance-vector and link-state protocols. It offers fast convergence, scalability, and efficient use of network resources. However, being proprietary, it may not be compatible with non-Cisco devices.

3. IS-IS (Intermediate System to Intermediate System): IS-IS is a link-state routing protocol that is commonly used in large service provider networks. It offers scalability, fast convergence, and support for multiple routing domains. However, it may require more complex configuration and management compared to other protocols.

4. BGP (Border Gateway Protocol): BGP is an exterior gateway protocol used for routing between autonomous systems (AS). It is highly scalable and flexible, making it suitable for large-scale networks with multiple ISPs. However, BGP is more complex to configure and manage compared to interior gateway protocols.

5. OSPF (Open Shortest Path First): OSPF is a link-state routing protocol that is widely used in enterprise networks. It offers fast convergence, scalability, and support for hierarchical network designs. OSPF is compatible with various vendors and provides efficient routing updates. It is a popular choice for complex global network infrastructures.

Considering the requirements of a multinational corporation with diverse geographical locations and the need for seamless communication between branches, OSPF would be a suitable choice. It provides efficient routing updates, scalability, and compatibility with different vendors.
