Description
For a generic routing encapsulation (GRE) tunnel, disable fragmentation of GRE-encapsulated packets. This sets the do-not-fragment (DF) bit in the outer IP header of the GRE-encapsulated packets so that they do not get fragmented anywhere in the path. When the size of a GRE-encapsulated packet is greater than the MTU of a link that the packet passes through, the GRE-encapsulated packet is dropped.
Default
By default, fragmentation of GRE-encapsulated packets is disabled.
