ARP Issues in EVPN Centralized Routing Design
Integrating IRB into EVPN MAC-VRFs, or stretched VLANs, involves adding IP addresses and possibly a shared anycast gateway, but poses challenges in multi-vendor environments, as discovered during EVPN lab exercises and integration tests.
MAIN POINTS
- Adding IRB to EVPN MAC-VRFs involves assigning IP addresses to VLAN interfaces.
- Optionally, a shared anycast gateway can be added to the setup.
- Challenges arise in multi-vendor environments when implementing these configurations.
- EVPN lab exercises and integration tests reveal issues with some EVPN implementations.
TAKEAWAYS
- Implementing IRB in EVPN MAC-VRFs can simplify network configurations.
- Multi-vendor environments complicate the integration of IRB with EVPN.
- Testing and lab exercises are crucial for identifying implementation issues.
- Network engineers should prepare for potential troubleshooting in complex setups.
