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.
