Configuring EVPN with Support for Virtual Switch

date_range 20-Dec-24

arrow_forward

You can configure an Ethernet VPN (EVPN) with virtual switch support to enable multiple tenants with independent VLAN and subnet space within an EVPN instance. Virtual switch provides the ability to extend Ethernet VLANs over a WAN using a single EVPN instance while maintaining data-plane separation between the various VLANs associated with that instance. A single EVPN instance can stretch up to 4094 bridge domains defined in a virtual switch to remote sites.

When configuring virtual switch for EVPN, be aware of the following considerations:

Due to default ARP policing, some of the ARP packets not destined for the device can be missed. This can lead to delayed ARP learning and synchronization.
Clearing ARP for an EVPN can lead to inconsistency between the ARP table and the EVPN ARP table. To avoid this situation, clear both ARP and EVPN ARP tables.
The vlan-tag can be configured for local switching. However, vlan-tagged VLANs should not be extended over the EVPN cloud.

Before you begin:

Configure the router interfaces.
Configure the router ID and autonomous system number for the device.
Enable chained composite next hop for EVPN.
Configure OSPF or any other IGP protocol.
Configure a BGP internal group.
Include the EVPN signaling network layer reachability information (NLRI) to the internal BGP group.
Configure RSVP or LDP.
Configure MPLS.
Create a label-switched path between the provider edge (PE) devices.

To configure the PE device:

Configure the virtual switch routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance instance-type virtual-switch

Configure the interface names for the virtual switch routing instance.
```
[edit routing-instances]
user@PE1# set evpn-instance interface interface-name
```

Configure the route distinguisher for the virtual switch routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance route-distinguisher route-distinguisher-value

Configure the VPN routing and forwarding (VRF) target community for the virtual switch routing instance.
```
[edit routing-instances]
user@PE1# set evpn-instance vrf-target vrf-target
```

List the VLAN identifiers that are to be EVPN extended.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance protocols evpn extended-vlan-list [vlan-id-range]

Configure the bridge domain for the first virtual switch routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains first-bridge-domain-name domain-type bridge

Assign the VLAN ID for the first bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains first-bridge-domain-name vlan-id 10

Configure the IRB interface as the routing interface for the first bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains first-bridge-domain-name routing-interface irb.0

Configure the interface name for the first bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains first-bridge-domain-name bridge-options interface CE-facing-interface

Configure the bridge domain for the second virtual switch routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains second-bridge-domain-name domain-type bridge

Assign the VLAN ID for the second bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains second-bridge-domain-name vlan-id VLAN-ID

Configure the IRB interface as the routing interface for the second bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains second-bridge-domain-name routing-interface irb.1

Configure the interface name for the second bridge domain.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance bridge-domains second-bridge-domain-name bridge-options interface CE-facing-interface

Configure the VRF routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set vrf-instance instance-type vrf

Configure the IRB interface as the routing interface for the VRF routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set vrf-instance interface irb.0
user@PE1# set vrf-instance interface irb.1

Configure the route distinguisher for the VRF routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set vrf-instance route-distinguisher route-distinguisher-value

Configure the VRF target community for the VRF routing instance.
```
[edit routing-instances]
user@PE1# set vrf-instance vrf-target vrf-target
```
Configure the VRF label for the VRF routing instance.
```
[edit routing-instances]
user@PE1# set vrf-instance vrf-table-label
```

Verify and commit the configuration.

For example:

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpna instance-type virtual-switch
user@PE1# set evpna interface ge-0/1/4.0
user@PE1# set evpna interface ge-0/1/4.1
user@PE1# set evpna route-distinguisher 10.255.169.37:1
