Configuring Packet Fragmentation on an MPLS P Node
This section describes how to configure packet fragmentation on an MPLS P node.
Background
A network with increasing scale and complexity allows for devices of various specifications. Without packet fragmentation enabled, an MPLS P node transparently transmits packets sent by the ingress PE to the egress PE. If the MTU configured on the ingress PE is greater than the MRU configured on the egress PE, the egress PE discards packets with sizes larger than the MRU.
In VS mode, this configuration task is supported only by the admin VS.
Procedure
- Run system-view
The system view is displayed.
- Run mpls fragment enable
MPLS fragmentation is enabled on a P node.
Packet fragmentation on the MPLS P node takes effect on MPLS packets that only have less than or equal to five labels and inner IPv4 labels.
- Run commit
The configuration is committed.
