Understanding Route Reflectors (RRs) in Huawei SD-WAN
In Huawei’sSD-WAN Solution, BGPRoute Reflectors (RRs)are used toreduce the number of BGP peer relationshipsand optimize routing scalability.
????Key Functions of an RR in SD-WAN:
CentralizesBGP route distributionin large-scale SD-WAN networks.
Reducesfull-mesh BGP peering complexity.
Improves network scalabilityand convergence time.
Analysis of Each Deployment Mode:
✅B. Independent deployment of the RR
Correct:The RR is deployed as astandalonedevice, independent of the SD-WAN hub site.
Best for large-scale SD-WAN deploymentsrequiring dedicated route control.
✅C. Co-deployment of the RR and hub site
Correct:The RR is co-located with the SD-WANhub site, reducing infrastructure overhead.
Best for mid-sized SD-WAN deploymentswhere thehub and RR functions can be combined.
✅D. Partially independent deployment of the RR
Correct:The RR ispartially separatedfrom the hub but still shares some resources.
Provides a balance between full independence and co-location.
❌A. Multi-area deployment of the RR (Incorrect Choice)
Multi-area RR deployment isnot a common Huawei SD-WAN practice.
Huaweidoes not require separate RRs per area, as SD-WAN is based oncentralized policy-based routing.
Real-World Application:
Large Enterprise SD-WAN:Usesindependent RRsto optimizeglobal network routing.
Service Provider SD-WAN:Usesco-deployed RRsto reduce infrastructure costs while maintainingroute scalability.
