+1. Short of platform specific side-effects it might cause like static buffering per MTU ranges causing available buffers to be significantly reduced when enabling large MTU. It is always good idea to set L2 and L3 link MTU to as large as they go, regardless if they match on ends or not, and then for L3 protocols which rely link MTU being same, set it in protocol level. -- ++ytti _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
