> Everything is working. If I ‘set mtu 9192’ everything breaks Just set the IP MTU in addition to the physical L2 "mtu". That way you don't have to care about calculating any possible differences caused by encapsulation overhead: set interface ... family inet mtu 9000 But how are you planning on overcoming the 1600 limitation on the TLS carrier? _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
