The correct answer is B. IBGP with BGP on loopback within each region and EBGP between the regions. Using iBGP with BGP on loopback within each region ensures scalable and stable routing inside the region, while eBGP between regions aligns with best practices to maintain clear boundaries, reduce convergence complexity, and support region separation.
Question
You are planning a new SD-WAN deployment with the following criteria:
- Two regions
- Most of the traffic is expected to remain within its region
- No requirement for inter-region ADVPN
To remain within the recommended best practices, which routing protocol should you select for the overlays?
Options
- AOSPF for the routing within each region and EBGP between the regions.
- BIBGP with BGP on loopback within each region and EBGP between the regions.
- CIBGP with BGP per overlays within each region and IBGP with BGP on loopback between the
- DIBGP within each region and between the regions.
