I’m not sure I entirely understand the purpose behind what you’re doing. I read the follow up message and still don’t quite get why you need a static to make this happen, but.. is the /32 thing because in JunOS by default doesn’t advertise /32s in EVPN? You can change this with policy in protocols evpn ip-prefix-routes export <blah>. https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/ref/statement/ip-prefix-routes-edit-routing-instances-protocols-evpn.html <https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/ref/statement/ip-prefix-routes-edit-routing-instances-protocols-evpn.html> -- Nathan Ward _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
