Industry Standards
While writing this book, we frequently shared thoughts with coworkers and fellow network engineers as a sanity check and a way to gather other perspectives. Of all the chapters we discussed, this one drew by far the most queries. The most common question was, “How in the world are you going to write that? Everyone knows that Juniper products don’t support EIGRP and HSRP.”
True statement. Juniper products do not support Cisco-proprietary protocols. However, both Cisco and Juniper products support implementations of industry-standard protocols such as Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and Virtual Router Redundancy Protocol (VRRP). Furthermore, while it is not considered a best practice, proprietary protocols are commonly found in some places in multivendor networks.
Actually, the “How?” question is rooted in a major misconception. People, even very experienced engineers, assume that when the terms system redundancy and multivendor are used to describe a network, the intention is to pair devices from different vendors within the architecture. This is not the case.
