Cisco IOS XE 17.13.1: Простая настройка EVPN Layer 2 Overlay CLI (EN)

Service Profile

BGP EVPN Layer 2 Overlay CLI Simplification You can now do away with multiple steps while provisioning the EVPN Layer 2 overlay. Cisco IOS XE 17.13.1 simplifies the CLIs and automatically sets default values for most of the common configurations. Simplified CLIs for Layer 2 Overlay Configuration, on page 1 Service Profile, on page 1 Simplified CLIs for Layer 2 Overlay Configuration Use the following set of CLIs to provision an EVPN Layer 2 overlay with three contiguous VLANs and the corresponding EVPN instances (EVIs). l2vpn evpn route-target auto vni ! vlan configuration 100-102 member evpn-instance ! interface nve1 no ip address source-interface Loopback2 host-reachability protocol bgp !

With the above configuration, the EVPN instance (EVI), EVI ID, and the VNI are auto-generated. The EVI ID is generated using the the EVI base and the VLAN ID. If an EVI base is not explicitly configured through a service profile , a default value of zero is assigned to it. By default, the encapsulation is set to vxlan and the replication-type is set to ingress . Service Profile A service profile represents a common set of characteristics that are shared by a group of services such as VLANs. A common set of characteristics that are shared by VLAN-based services can be replication-type, EVI mapping, VNI mapping, route-target mapping, and so on.

The member evpn-instance and l2vpn evpn CLIs are enhanced to provide an optional profile profile-name keyword to group the common characteristics of an EVPN instance. l2vpn evpn profile { default | profile-name } BGP EVPN Layer 2 Overlay CLI Simplification 1

Service Profile

If you do not provide a profile name and its definition, a default EVPN profile is created. Use the show l2vpn evpn profile default command to see the default profile values. Leaf1# show l2vpn evpn profile default detail EVPN Profile (VLAN Based): default (auto) evpn id base: 0 l2 vni base: 20000 Encapsulation: vxlan Replication Type: Ingress IP Local Learn: Not set Flooding Suppression Address Resolution: Not set Adv. default-gateway: Not set Adv. Multicast: Not set RT5 Re-originate Flag: Disabled Local Routing: Not set vlan(s): 101-102,111-114,131-132 Leaf1# The following shows how to create an EVPN profile and use it.

When this CCTV profile is applied to an EVPN instance through the member evpn-instance profile CCTV command, the EVPN instance inherits all the definitions under the CCTV profile.
