IP Fragmentation and Reassembly on L2GRE and GMIP Tunnels

Starting in software version 4.6, L2GRE and GMIP tunnels support IP fragmentation and reassembly of packets. IP fragmentation can occur with encapsulation. Fragmented packets are sent on the tool port at the sending end of the tunnel (for example, at a remote site). IP reassembly occurs with decapsulation. Fragmented packets reaching the network port at the receiving end of the tunnel (for example, at a main office site), are decapsulated and reassembled before being sent to a destination.

Refer to the “IP Fragmentation and Reassembly on L2GRE and GMIP Tunnels” section in the GigaVUE Fabric Management Guide for more details.
