Results Summary and Analysis

The JVD team has successfully validated the comprehensive multidimensional solutions for the proposed SRv6 architecture by executing extensive test cases developed for this design. The validation uses Juniper Networks MX304, MX480, MX2010, MX10004, and PTX10002-36QDD as primary DUTs. Over 100 test cases are executed for each DUT during validation on Junos OS and Junos OS Evolved version 24.4R2.

The objective of this JVD is to create practical solutions with a multidimensional scale relevant to the domain-specific use cases. Functional testing ensures that services and protocols operate within expectations. This JVD measures and reports the network resiliency and convergence performance.

General testing includes, but is not limited to, the following scenarios:

  • Validate end-to-end service provider network architecture and design with SRv6 mSID as a foundation technology under scale during normal operations and under multiple stress conditions.
  • Validate MX with mkernel (for example, Trio 4: EA chip) PFE and MX with AFT (for example, Trio 5: ZT chip) PFE, as platforms for Edge (EDGE).
  • Validate PTX10002-36QDD (Express 5: BX chip) and MX with AFT (for example, Trio 6: YT chip) platforms as border node (BR).
  • Validate MX with AFT (for example, Trio 5/6: ZT/YT chip) PFE, as platforms for Multi-Service Edge (MSE).
  • Validate solution scaling documented in Table 1 .
  • Validate solution resiliency during any single link or node failure.
  • Execute various resiliency tests for routing protocols convergence IS-IS or BGP.
  • Restore device configuration.
  • Reboot devices.
  • Restart various Junos OS and Junos OS EVO software components.

Scaling of JVD Testing

Note:

The information shared in this section does not represent system maximums and may be modified at any time. Contact your Juniper Networks representative for additional scaling information.
Table 1: Scaling for JVD Testing
Scaling Values
Feature Scale
Node SIDs (mN) 3000
Adjacency SIDs (mA) 9000
SRv6 Locators 9000
EVPN VPWS instance 4000
SRV6-L3VPN (µDT4/µDT6/µDT46) 8000

The scaling details shown in Table 1 are used for resiliency and functional testing in the JVD.

The network design validated in this JVD delivers fast network restoration in an SRv6-based network. Based on TI-LFA and MLA, traffic flows are rerouted with minimal impact.

Convergence Measurements

Table 1 shows convergence measurements for link failures and restoration times. Results show the expected value for total restoration time. Core SRv6 topology fast restoration (TI-LFA) mitigates core link failures. The backup core path is preprogrammed in the PFE of each transit node, enabling traffic to recover within milliseconds. The results reflect rapid link restoration times achieved by IP FRR (SRv6 TI-LFA) for the underlay network.
