[j-nsp] evpn trouble

[Roger Wiklund]

Hi

What data plane are you using, MPLS or VXLAN?

Instance-type evpn is VLAN-Based Service. I.E one VLAN per EVPN instance,
is this what you want?

If you want to run multiple VLANs in one EVPN instance you can use
VLAN-Aware Service (instance-type virtual-switch or in default
virtual-switch) where each VLAN/VNI will have a unique RT.

With that said from Junos 20.4R1 there's a new mac-vrf instance-type where
you can more clearly define the different services
instance-type mac-vrf
service-type vlan-aware / vlan-based / vlan-bundle

Not sure when MX/ACX will gain this feature though.

Roger
