Packet out of sequence Query

[nilesh_sawant]

Hi, In our MPLS network we are planning two add one more WAN link between two nodes of same bw as of existing link, say two WAN link of 200Mbps. As a IGP we are running OSPF and MPLS enabled on the WAN. If the traffic gets load balance on both the parallel link then will the packet out of sequence issue appears ?

If this is introducing the packet out of sequence issue then is there any way to avoid the same but have to use both the wan link for the traffic flow.

Need the information

.

Regards,

Nilesh

Hello Nilesh,

load balancing is flow based also on an MPLS network.

Load balancing criteria of MPLS frames is based on internal MPLS label (VPN label) for MPLS L3 VPN service.

In any case, whatever is the type of MPLS service there will not be out of order issues as load balancing will be flow based and packets belonging to the same flow will be switched over the same path

Hope to help
