Policies and the Thousand Implementations

Summary: 
There are literally hundreds of different ways to use policies on your routers. I like the generic policies used in long policy chains. Some people like the very specific policies with 100 terms. Some people like it somewhere in the middle. It's really a matter of taste....or is it?

Here are some policy examples that would all accomplish the same thing for an External BGP Peer advertising many routes including the default 0/0 route. What we want to do is reject all routes and only accept the default route from our peer.

 

1 Policy, 2 Terms

accepts and rejects in the same policy

The New Global Language

Summary: 
Resident Rockstar Ben Boyd takes us around the world to explore a truly global language, Junos!

Everyone has always said that math is the global language.  It's true.

No matter where you go in the world, 1+1=2 is expressed the same way and means the same thing everywhere.

I've found an additional global language after traveling to several continents over the past few years implementing Juniper data center, campus, enterprise, and service provider solutions. JUNOS is a global language.

show chassis cluster status means the same in Singapore, Tel Aviv, Mexico City, Bogota, and Sydney (yes, I know they speak English there).
