EVPN

Support for EVPN-VPWS over SRv6-TE and SRv6 with micro-SID (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, and ACX7509) —

Starting in Junos OS Evolved Release 24.2R1, we support the following Segment Routing for IPv6 (SRv6) underlay features with EVPN-VPWS on the ACX7000 family:

• SRv6-TE tunnels without fallback support—With SRv6-TE, you can assign traffic flows to different networking SRv6 tunnels based on a customer's traffic service requirements.

  [See Overview of VPWS with EVPN Signaling Mechanisms, Configuring EVPN VPWS over SRv6 with Traffic Engineering, and Configuring EVPN over Transport Class Tunnels.]

• SRv6 with micro-SIDs—With micro-SID, you can compress multiple Segment Routing for IPv6 (SRv6) addresses into a single IPv6 address (the micro-SID and reduce bandwidth overhead.

  [See Configuring Micro-SIDs in EVPN-VPWS.]

Support for EVPN-MPLS (ELAN and IRB) over colored and non-colored SR-TE (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, and ACX7509)—Starting in Junos OS Evolved Release 24.2R1, we support EVPN services with underlay as SR-TE Policy over colored and non-colored SRTE. To configure colored SR-TE, include the preserve-nexthop-hierarchy statement at the [edit routing-options resolution] hierarchy level.

This feature also supports EVPN asymmetric IRB over SR-TE. If you use Layer 3 (L3) gateway functionality with EVPN, asymmetric IRB flow over SR-TE doesn't work in a single pass. Therefore, asymmetric IRB flow uses a recycle path. The recycle handling requires specifying a recycle port and bandwidth. Thus, traffic over  EVPN asymmetric IRB over SR-TE is restricted to the available recycle bandwidth.

To reserve the bandwidth for EVPN IRB asymmetric flow, use the following configuration under recycle-bandwidth-profile to allocate a bandwidth:

You can set the value for the evpn-irb bandwidth in the range of 1 through 100.

Use the following configuration to activate the recycle bandwidth configuration:

Use the following command to check the existing bandwidth usage:

If you do not reserve a bandwidth for the EVPN IRB application, the EVPN IRB application shares bandwidth with other recycle applications.

The following scenarios are supported:

• EVPN-ELAN over non-colored SR-TE without preserve next-hop hierarchy

• EVPN-ELAN over non-colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN single homing over colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN A/A multihoming homing over colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN A/S multihoming homing over colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN IRB symmetric over colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN IRB asymmetric over colored SR-TE with preserve next-hop hierarchy

• EVPN-ELAN over static SR-TE tunnel

• EVPN-ELAN over dynamic (DTM) SR-TE tunnel

• EVPN ELAN over SR-TE LSP path redundancy

• EVPN ELAN over SR-TE LSP and IGP redundancy

• EVPN aliasing over SR-TE with SR-TE and IGP-level redundancy

• EVPN IRB asymmetric over aliasing with SR-TE and IGP-level redundancy

• BGP-LU over SR-TE (non-preserve next-hop hierarchy mode only)

• Flow label over SR-TE

• NSR support for EVPN over SR-TE (SH, MH, IRB)
