QoS in IPSec tunnel over MPLS

Answered Question
Apr 24th, 2014
User Badges:
Dear All, I am planning to configure IPsec Tunnel over MPLS connectivity from the service provider. IPsec tunnel is configured between WAN interfaces of the CPE's at all locations. As per my understanding IPSec encrypts all traffic going inside the tunnel. But I need to configure QoS ,so that in service providers network my data should be prioritized. Is it possible to prioritize traffic inside the tunnel? please suggest.. Thanks, Raghavendra

Generally, by default, Cisco tunnel encapsulation will copy the original packet's ToS to the tunnel packet's ToS.  (I.e. all you need to do is insure your original packet's ToS is as desired.)

 

Regarding MPLS vendor QoS support - that's vendor specific - often they offer different QoS models - sometimes they charge for QoS features (i.e. you need to talk with them).
