Recommendations

ACX710 Universal Metro Router can be recommended as CSR in small to midsize 4G/5G MBH applications with access segments consisting of 50-70 access nodes per IGP domain (multiple IGP domains can comprise the access and aggregation segments). ACX5448 Universal Metro Router can be used in equivalent and expanded roles, including pre-aggregation and aggregation for midsized engagements.

Seamless segment routing is a recommended underlay architecture to support end-to-end stitching with BGP-LU and BGP-CT transport classes across multiple IGP and inter-AS domains. Using TI-LFA and ECMP mechanisms, the solution supports rapid failover and resilience. Network pre-slicing is accomplished with color-mapping overlay services (L3VPN, L2VPN, and L2Circuit) to Flex-Algo underlay tunnel slices. In parallel, color agnostic services coexist, taking advantage of the same infrastructure. Both ACX710 and ACX5448 Universal Metro Routers support these protocols and services to enable end-to-end converged 5G MBH.

This JVD uses Junos OS Release 21.2R3 as a minimum version to support the validated design.

Contact your Juniper Networks representative for the full test report with details about convergence times for all failure events.

While the reference design of this JVD is the converged xHaul infrastructure, the technologies and practical solutions covered can be leveraged as building blocks from which additional designs might evolve to support multidimensional network architectures.
