EVPN MPLS on Cisco IOS XE&XR

Compare layer 2 VPN concepts, and see how MPLS carries layer 2 VPN traffic with protocols like BGP or LDP, while the provider acts as a switch.

Discover how layer 2 vpn multihoming delivers load balancing and redundancy across pe routers, and learn all active, port active, and single active topologies with port channel and vlan distribution.

EVPN vs VPLS hinges on MAC learning: data-plane learning in legacy VPNs versus BGP layer 2 updates in EVPN, with MPLS labels distributed to peers.

Examine why all-active VPLS forwarding causes broadcast loops, duplication, and MAC flip-flop in multihomed EVPN deployments, and how VPNs with a separate control plane mitigate these issues.

Compare EVPN and VPLS on Cisco IOS XE/XR, showing how a BGP-only control plane enables both layer 2 and layer 3 VPN services, with seamless EVPN to VPNv4/v6 translation.

Demonstrates ios xe/xr evpn mpls configuration for all-active multihoming with ethernet segment identifiers, service instances, bridge domains, and layer 2 vpn using bgp control plane.

Designated forwarder election in multihomed evpn mpls ensures only the DF forwards boom traffic, while non-DF drops duplicates using a modulo-based scheme.

Discover how designated forwarders use per-peer boom labels advertised by neighbors to forward boom traffic, with P1 10,004 and P5 50,004, via evpn route type three and ingress replication.

This lecture explains aliasing labels in EVPN MPLS, showing how per-ESI and per-BD labels enable load balancing for multihomed C1 across P1 and P2.

Review evpn mpls on ios xe&xr, detailing esi advertisement via bgp route types, gsi in multihoming, designated forwarder election, bloom and split horizon labels, and mac-to-mpls mapping for load balancing.

Set up evpn mpls on ios xe and xr labs, starting with day-one igp and ldp configurations, then apply vpn configurations for multi-homed and single-homed topologies.

Configure evpn mpls on ios xe using ospf and ldp to establish end-to-end lsp reachability and deploy vlan ten with vpn instance 125.

Explore ios xe xr evpn mpls lab outputs, validating bgp vpn route types, df election, split horizon, mac learning, and the service provider network behaving as a single switch.

Configure evpn mpls on ios xr, detailing layer two vpn service, evi, advertise mac, and bgp for single-active and single-homed esr, noting xv9 bridge domain and xserve bundled ethernet limits.

Demonstrates IOS XR outputs for EVPN MPLS, detailing DF election, boom label advertising, split horizon, and MAC learning behavior for EVI forwarding.

Deploy vpn mpls on esr with an eks-like topology, using CSR 1000V devices, multihomed g and c with a single active setup, and evpn configuration.

Configure evpn mpls on ios xr by enabling layer two vpn transport, advertising mac via bgp route type two, and establishing a bridge group with an esi for vpn 125.

Explore how evpn mpls on Cisco ios xe&xr enables integrated routing and bridging, uniting layer two forwarding with layer three routing via irb, bridge domains, and distributed anycast gateways.

Explains evpn irb configuration with vcf, route targets, and stitching to generate bgp route type five for vpnv4, covering vrf, interfaces, and l2vpn l3vpn redistribution across bd1 and bd2.

Explains how EVPN IRB and L3VPN outputs create reachability between C1 and C2 using VRF Pepsi, BDI, VPN before unicast, BGP route type five, and stitching route targets.

Demonstrate an ios xe lab for evpn irb and l3vpn using the d3 topology, configuring bridge domains, service instances, bgp evpn routes, and stitching to verify l2 and l3 reachability.

Introduce the point-to-point evpn vpws (e-line) model, contrast it with multipoint lan emulation, and explain its simple forward logic and bgp type 1 auto-discovery.

Configure evpn vpws on ios xe xr for a point-to-point virtual circuit using evi, virtual wire service context, and vlan tags, with l2vpn bgp address family activation across pes.

Explain EVPN VPWS on IOS XE using BGP route type 1 to advertise the service with router distinguisher, local service value, and MPLS label for a virtual circuit.

Set up a point-to-point evpn vpws tunnel on IOS XE XR for a single-homed lab, configure service instance and vpn, then verify evpn routes, labels, bgp state, and vc status.

Configure a layer 2 vpn using evpn vpws on ios xr, with l2 transport on a subinterface, vlan matching, and bgp address-family and neighbor settings for evi and service values.

Configure the day-one evpn vpws lab on iOS XR by enabling a layer-2 transport interface on VLAN ten and configuring the layer-2 vpn address family with a neighbor.
