Hi,

We have three sites all connected via MPLS running BGP.

We are planning to use DMVPN over MPLS for all the above three sites.We want to have hub & spoke topology.We wanted to decide on the routing protocol to be used within the DMVPN tunnel.We wanted to run either EIGRP or OSPF.

We wanted to know the foll.

1.Advantages & disadvantages of using EIGRP in the tunnel.

2.Advantages & disadvantages of using OSPF in the tunnel.

Rgds.

Sack, the answer will really depend of your goals and network design, I think you would rather check out the white papers from Cisco about DMVPN and scalability and design:

The main advantage of OSPF is that its based on open standards, so if you decide to migrate to some other vendor you would not be stuck with a proprietary technology (eigrp). However Cisco recommends EIGRP for DMVPN, see pg 2-9 on the below PDF:
