Summary of BGP Unnumbered EVPN Fabric NCE

Congratulations! You configured and validated a BGP unnumbered fabric based on IPv6 and eBGP. This underlay is now ready to support your choice of EVPN-VXLAN overlay. Table 1 details your accomplishments.

Table 1: Summary of Accomplishments

Configured BGP unnumbered peering for an EVPN-VXLAN fabric.

In this step, you configured the fabric devices to support IPv6 unnumbered peering. Only minimal interaction is needed to add the inet6 family on the fabric interfaces and to define a BGP peer group that supports automatic peering.

Junos OS support for a routing policy that defined the allowed range of automatic peering AS numbers, and configuration groups, greatly reduces the configuration size and complexity needed to deploy large fabrics.

Validated the operation of a BGP unnumbered underlay

You confirmed link-local addressing, IPv6 router advertisements and neighbor discovery. You verified dynamic IPv6 BGP peering to link-local addresses. You also confirmed the expected loopback route exchange needed to support an EVPN-VXLAN overlay.

Next, you'll want to add the EVPN-VXLAN overlay. Refer to Configure IBGP for the Overlay for details on adding an overlay.
