S01E04 Full Internet View on “Base” NCS 5500 Systems
Previously on “Understanding NCS5500 Resources”
In previous posts, we presented:
- the different routers and line cards in NCS5500 portfolio
- we explained how IPv4 prefixes are sorted in LEM, LPM and eTCAM
- and how IPv6 prefixes are stored in the same databases.
Let’s illustrate how we can handle a full IPv4 and IPv6 Internet view on base systems and line cards (i.e. without external TCAM, only using the LEM and LPM internal to the forwarding ASIC).
The demo
Following YouTube video will demonstrate we can handle multiple internet peers in the global routing table (15 full views on our demo) on base systems with the appropriate optimizatios.
We will demo how we can monitor the important resources used to store routing information and finally we will project what could be the internet size if it follows 2017 trends and how long the systems will be handle the full v4/v6 views.

This video shows NCS5500 using Jericho-based line cards without external TCAM (also valid for fixed-form systems) handling the current internet table with still significant growth margin.
Config and CLI
On this line card we have:

Which gives us the following graphs:
We can extrapolate the route count in LEM and LPM now.

| 2018 | 592543 | 296045 |

| 2024 | 873349 | 425389 |
| 2025 | 920150 | 446947 |
It’s certainly a very simplistic approach, feel free to provide other sources or your own growth projection in the comments, we will re-do the math with it.
