Greetings, ive been tasked with putting together an MPLS solution for one of my customers.
We were originally going to be using individual WAN links and running a DMVPN on top for routing and security between sites.
There will be 1 HO and 8 remote sites, a single ASA 5510 and 3800 ISR will sit at the HO and 2800 ISR's at all other sites.
The HO will have a single leased line terminating on ethernet and all other sites will be on SDSL.
Im semi aware of the capabilities of MPLS and that peering is normally achieved by using BGP, OSPF, RIPv2 etc but haven't any practical experience of configuring a collection of routers for customer sites.
If someone could answer the questions below it would be much appreciated.
1. Do all routers at customer sites run BGP or other dynamic routing protocols to advertise there internal networks into the cloud or is just one router namely the HO Router run BGP and all other sites use statics to enter the cloud?
2. I continually see references to Layer 2 and Layer 3 (IPVPN) MPLS designs, can you utilise a Later 2 MPLS Network and run IPSec/GRE on top for security and routing purposes?
3. Is MPLS a fully meshed topology by default or is a requested feature?
4. Are there any CE router configuration examples available to see a real world configuration?
Any help would be much appreciated.
