Quite a simple lab this one. A customer wants to establish IPv6 connectivity between 2 sites over our SR IPv4 core so IPv6 tunneling is required. 2 Cisco vIOS routers used as the CE devices.

Routes are now being learned from the other CE device and IPv6 connectivity is up between the 2 sites.

A change with this lab as RSVP will be used as the MPLS signalling protocol. IS-IS for the IGP and Cisco vIOS again used as the CE devices

The VPLS circuit will now be up.

OSPF has been configured to the Cisco devices but you could chose another protocol if you prefer.

Cisco vIOS switches used as the CE devices and a LAG between them and the PE vMX’s. IS-IS for the underlay and LDP for the label distribution. You could use RSVP or Segment Routing if you prefer.

VPWS instance will now be up. OSPF has been configured on both CE devices and relatiionship is up

You will need a trial license from Juniper for this lab, which can be obtained from the below URL.

https://www.juniper.net/gb/en/dm/vmx-trial-download.html

BGP is used between the CE & PE devices. Could use OSPF but would then need a sham link between CE devices to stop routes being shown as external routes.

The L3VPN will now be up and the CE devices receiving routes from each other. You may need to reboot the vMX devices before you see the routes.

Establish a layer 2 circuit between the 2 CE devices, traversing 3 separate AS’s.

OSPF has been configured on both CE devices and a neighbourship has formed confirming that the layer 2 circuit is up.

This topology is Option C utilising BGP-LU. IS-IS in the underlay and OSPF between the 2 CE Cisco devices. Can use other devices as CE’s if you prefer.

Your CE’s will now have a layer 2 circuit between them. In this example, OSPF has been configured on them and you can see from the routing tables that an adjacency has formed and they are learning each other’s routes.

An example Juniper L3VPN configuration example. IS-IS underlay and BGP between PE’s & CE’s.

BGP is configured between the CE & PE devices and loopbacks have been configured on the CE’s with addresses of 111.111.111.111 & 222.222.222.222 respectively. These are being redistributed into BGP and you should now see the opposing loopback in the route table.

A very simple topology for this one. 3 vMX devices, 2 Arista vEOS acting as the CE devices (you can use other devices if prefer) and 2vPC’s to confirm IP connectivity. 55 is the C-Tag, 110 the S-Tag

Configure IP addresses from the same subnet on both of the vPC’s and they should be able to ping each other. The below image of a Wireguard capture shows the double VLAN tags when ping is sent.

MPLS EVPN is slightly different on JunosEvolved as it uses a mac-vrf routing instance rather than an evpn instance. A lot of similarities though and topology and EVE NG import below. 2 Cisco vIOS switches used as CE’s but pick your poison and use whatever you prefer. An OSPF neighbour adjacency has been established between them confirming the EVPN circuit is up.

Your EVPN circuit should now be up and running. Terminal screenshot below showing that OSPF adjacency has been established. You could choose IS-IS, BGP or even EIGRP if using Cisco devices for the CE’s as it’s just a layer 2 circuit between them.
