## routing - directly connected routing
- Creates two network namespaces c1, c2
- A gateway interface for each on VPP
- Routes due to directly connected routes inserted into default FIB

## bridging - directly connected interfaces into a bridge-domain
- Creates two network namespaces c1, c2
- Adds interfaces to VPP and add them to bridge-domain 1
- MAC addresses are automatically learned

## tracing - how to show a "day in the life of a packet" in VPP
- Same environment as "routing" demo
- How to add a trace
- View a trace
