Alright, we know you’re hungry for more Cumulus goodness, so we’ve cooked up something new that we think will satiate your appetite for awesome technical content. It’s the perfect mix of one part technical deep-dive, one part fun and just a pinch of silliness. The wait is over — our latest project is hot, fresh and ready to serve!

Okay, enough teasing. Today we’re introducing the new Cumulus Networks video series “Cooking with Cumulus!”

“Wait, what does cooking have to do with networking??” you may think to yourself. Glad you asked. You may already know JR Rivers as the CTO and co-founder of Cumulus Networks, but did you know he’s also a master of the culinary arts? Here at the Mountain View office, we know it’s the start of a good day when JR brings in his homemade food to share. From chocolate chip cookies to paella, we’ve approved (and enjoyed) his many recipes. So, we decided that we wanted to share that gift with the rest of the Cumulus community by combining two of JR’s greatest passions — networking and cooking. The resulting brain child was a video series where we put two networking nerds in a kitchen and let them connect the delicious dish they crafted to their favorite techie topics. Thus, “Cooking with Cumulus” was born. I haven’t seen JR this excited about a project since EVPN on Cumulus Linux!

In our pilot episode, we decided to focus on the capabilities of layer 3 architecture. And what better dish to illustrate the benefits of effective layering than tacos? Chef de cuisine JR is joined by sous chef and Technical Marketing Engineer Pete Lumbis as they construct some delicious fish tacos and chat about their favorite layer 3 use cases. Some of the layer 3 networking benefits they discuss in this episode include:

  • The ability to run everything in the infrastructure with just one topology protocol
  • Easier configurations, deployment and maintenance
  • Fewer network outages due to L2 complexities
  • And more!

Forget about the Food Network! Watch the premiere episode of “Cooking with Cumulus,” and you’ll become an expert on both cuisine AND open networking.

We’ve also included the recipe here so you can try making your own layer 3 networking tacos at home! Be sure to share photos of your culinary creations with us on Twitter (@CumulusNetworks) and send us recipes for the data center-related delicacies you’ve concocted as well! Think about the possibilities — you could make chassis cheesecake, or BASHed potatoes, or FRRench fries, or…

Sorry, I’ll stop with the puns now.

For those who want to add the instructions to their recipe book, we’ve got a handy printable version just for you. Don’t worry, we won’t tell your friends that it’s not ACTUALLY your grandma’s secret recipe!

Layer 3 Fish Tacos Recipe


2 Jalapeño peppers, seeded, ribbed, & finely diced
1/4 Onion, diced
Fresh lime juice
Avocado, sliced or cubed
Grated cheese
Red cabbage, thinly sliced

1 Halibut fillet, de-skinned and cut into 1 inch cubes
Corn tortillas
Olive oil
2 Parts paprika
1 Part Cayenne pepper
1 Part Chili powder
1 Part Garlic powder
Salt & pepper to taste


1. Prepare salsa — Place diced jalapeños and onion in a non-reactive bowl. Submerge mixture in fresh squeezed lime juice, and set aside.

2. Lightly coat halibut in olive oil. Rule of thumb: keep one clean hand and one dirty hand when working with raw meats.

3. Prepare seasoning mixture — Combine paprika, cayenne pepper, chili powder, garlic powder, salt and pepper. Mix together, and sprinkle on halibut, distributing evenly.

4. Warm tortilla — Preheat a skillet over medium heat. Rub a small amount of water onto each side of the tortilla. Place in skillet, heating each side for 20-30 seconds. Remove from heat and place on covered plate to keep warm and moist.

5. Cook halibut — Preheat a skillet over medium high heat and coat with olive oil. Cook halibut in batches, placing a single layer of fish into skillet. Turn sparingly, cooking for 4-5 minutes until fish is opaque. Remove from heat and place in bowl.

6. Build tacos with desired toppings. Add hot sauce of choice for a little kick!
