The document provides an overview of updates to Juniper's MX platform, including new line cards and interface options for increased scale and performance. Key points include: - New MPC5E and MPC6E line cards that provide increased throughput and interface flexibility with options like 100G interfaces. - Software features for increased routing scale, virtualization support, and packet performance optimization techniques like "hypermode forwarding" and "turbo filters." - A next generation port extender architecture for simplifying management of satellite devices connected to MX routers. - EVPN and VXLAN support for using MX routers as data center gateways in multi-tenant cloud environments.

6. Reducing provisioned chassis power
Configuration
chassis {
ambient-temperature 25C|40C|55C;
}
Goal
Reduce provisioned system power for most of the router deployments
Support more line cards
Version
MX2K:13.3R4
MX960, MX480, MX240: 13.3R6
Solution
By default the power is provisioned for the worst case (55C), instruct the system
to provision less
Support 11 x MPC4E or 11 x MPC5E in a chassis

7. Routing system upgrade scenario
