clear-dont-fragment-bit (fti)


Hierarchy Level


Clear the Don’t Fragment (DF) bit on all IP version 4 (IPv4) packets entering the (UDP/GRE/IP-in-IP) tunnel on FTI interfaces. If the encapsulated packet size exceeds the tunnel maximum transmission unit (MTU), the packet is fragmented before encapsulation.

When the option is not configured and the DF bit is set, the packets will be dropped if the packet size is larger than the MTU of the FTI.
