A VxBlock 1000 system is being deployed at a customer site. The system is equipped with a Nexus 93180YC aggregation switch to support routing features. A Juniper switch is used at the customer site as the core switch. The customer intends to run a dynamic routing protocol between the Nexus and Juniper switches. Which routing protocol is recommended?

Review the VxBlock and Nexus Documentation: The VxBlock 1000 system documentation and the Nexus 93180YC switch documentation should be reviewed to understand the supported routing protocols1. Consider the Juniper Switch Capabilities: Since the customer is using a Juniper switch as the core switch, it’s important to consider the routing protocols supported by Juniper switches. Juniper switches support a variety of routing protocols, including OSPF2. Evaluate Routing Protocol Options: EIGRP is typically Cisco proprietary and not supported on Juniper devices. IGMP is not a routing protocol but a multicast management protocol. IGRP is an older Cisco proprietary routing protocol and is less commonly used today2. Recommend OSPF: OSPF (Open Shortest Path First) is a widely supported, robust, and scalable dynamic routing protocol that is suitable for diverse environments, including mixed vendor setups like Cisco’s Nexus and Juniper switches2. Validate with Best Practices: Best practices and recommendations from both Cisco and Juniper suggest using OSPF for dynamic routing between devices from different vendors2.
