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.
