Juniper Labs Routing

Routing Configuration Overview

When we have connectivity from one logical system to another, it’s time to configure dynamic routing to ensure full end-to-end connectivity.

In this lab section, we will cover several dynamic routing protocols:

1. ACX1100
   Provides WAN (Internet/home lab) access to all other systems via source NAT.

2. OSPF (ACX1100, LRC)
   Exchanges routes in area 0.0.0.0.

3. iBGP (LRC, LR1, LR2)
   LRC acts as a route reflector for LR1 and LR2, exchanging routes within AS 65501.

4. eBGP (LRC, LR3)
   Exchanges routes between AS 65501 and AS 65502.

5. IS-IS (LR3, FRR-arm64)
   Exchanges routes in area 49.0002.

End Goal:
All networks must be visible across every logical system and the ARM64 SBC—regardless of which routing protocol is in use—and every node must have Internet access.
