You have to set the mtu at the physical interface level. You must also account for the L2 overhead tho. Meaning if you want 9000 byte mtu for ip you need to set the physical ethernet interface to 9014. If you set the physical to a higher parameter the family will inherit the MTU as well. Meaning you wouldn't have to code 9000 if that is the mtu you wanted.

Any help would be much appreciated Thanks, Brian _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp Sent via BlackBerry by AT&T _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
