MPLS consideration for Intercluster Trunk

Unanswered Question

Hello Andres,

with a good configuration there will be no impacts.

Aspects to be verified when activating MPLS service:

test MTU : verify if ip packets with MTU = 1500 Bytes and DF set can travel between the two sites

check QoS: verify that your provider allows the MPLS EXP bits to be a copy of the TOS bits, or if there is a DSCP byte to MPLS exp mapping. This is similar to QoS trust in LAN switches.

It is useful to provide better service to VoIP RTP streams (LLQ) and to signalling packets

Hope to help
