[j-nsp] VXLAN connection through the third-party operator’s network

[Łukasz Trąbiński]

Hello

Has anyone tried to establish a VXLAN connection through a third-party provider (e.g., Arelion)?
Apart from the standard configuration, what else should be taken into account? A smaller MTU, perhaps?

I have created three routing instances:
    • WARDC (mac-vrf)
    • vrf-internal
    • vrf-public-external

In vrf-public-external, I have a connection to the Arelion provider (with the full BGP table and a 0.0.0.0/0 prefix).
In vrf-internal, I created an irb.668 interface with the address 192.168.68.1/24.

I would like to create VLAN/VXLAN 668 linking vrf-internal with the remote network terminating on the Arista device at xxx.xxx.xxx.xxx. The connection is established via loopback interfaces:
    • Juniper: lo0.100 with address public_ip/32
    • Arista: public_ip/32

The Arista IP is reachable from vrf-public-external. It’s not working I don’t have idea why. In vrf-internal I have also 0.0.0.0/0 leaked from vrf-external-public.
On both sides i have working internally vxlan configuration.
It is possibe to do something like this?
