Question about Tunnelling OSPF over MPLS managed WAN

[davidjkent]

Hi,

My company have recently installed a managed MPLS WAN service. In order to continue using OSPF as our routing protocol across our Wans I set up GRE tunneling on our routers. We need to implement COS/QOS for VIOP traffic However I am not particularly familiar with GRE and need a few things clarifing.

1. Does all traffic crossing the WAN get encapsulated in the GRE tunnel? If so how can QOS be applied.

2. If I can configure our routers to only pass OSPF traffic via the GRE tunnel and everything else in the clear how do I do this?

Many Thanks for your assistance
