Configuring EVPN with IRB Solution

date_range 20-Dec-24

arrow_backward

arrow_forward

You can configure an Ethernet VPN (EVPN) with IRB solution to enable Layer 2 switching and Layer 3 routing operations within a single node, thus avoiding extra hops for inter-subnet traffic. The EVPN IRB solution eliminates the default gateway problem using the gateway MAC and IP synchronization, and avoids the triangular routing problem with Layer 3 interworking by creating IP host routes for virtual machines (VMs) in the tenant virtual routing and forwarding (VRF) routing instances.

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 EVPN routing instance.

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

Set the VLAN identifier for the bridging domain in the EVPN routing instance.
```
[edit routing-instances]
user@PE1# set evpn-instance vlan-id VLAN-ID
```

Configure the interface name for the EVPN routing instance.

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpn-instance interface CE-facing-interface

Configure the IRB interface as the routing interface for the EVPN routing instance.
```
[edit routing-instances]
user@PE1# set evpn-instance routing-interface irb.0
```

Configure the route distinguisher for the EVPN 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 EVPN routing instance.
```
[edit routing-instances]
user@PE1# set evpn-instance vrf-target vrf-target-value
```

Assign the interface name that connects the PE device site to the VPN.

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

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 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 evpn
user@PE1# set evpna vlan-id 10
user@PE1# set evpna interface ge-1/1/8.0
user@PE1# set evpna routing-interface irb.0
user@PE1# set evpna route-distinguisher 192.0.2.1:100
user@PE1# set evpna vrf-target target:100:100
user@PE1# set evpna protocols evpn interface ge-1/1/8.0
user@PE1# set vrf instance-type vrf
user@PE1# set vrf interface irb.0
user@PE1# set vrf route-distinguisher 192.0.2.1:300
user@PE1# set vrf vrf-target target:100:300
user@PE1# set vrf vrf-table-label

content_copy zoom_out_map
[edit]
user@PE1# commit
commit complete

To configure an ACX series router running Junos OS Evolved as the PE device in an EVPN-ELAN vlan-based routing-instance with IRB, verify and commit the following configuration:

content_copy zoom_out_map
[edit routing-instances]
user@PE1# set evpna instance-type mac-vrf
user@PE1# set evpna protocols evpn normalization
user@PE1# set evpna service-type vlan-based
user@PE1# set evpna route-distinguisher 192.0.2.1:100
user@PE1# set evpna vrf-target target:100:100
user@PE1# set evpna vlans v-500 vlan-id 10
user@PE1# set evpna vlans v-500 interface ae0.0
user@PE1# set evpna vlans v-500 l3-interface irb.0
