GRE Fragmentation and Reassembly

You can configure the generic routing encapsulation (GRE) tunnel interfaces to support IP packet reassembly. You can configure the GRE interfaces to reassemble the fragmented packets at the endpoint of the tunnel before they can be further processed on the network by including the reassemble-packets statement at the [edit interfaces gr-fpc/pic/port unit logical-unit-number] hierarchy level. You can view the reassembly statistics by using the show services inline ip-reassembly stastics command.
