MPLS related Notes

• Senario, start adding a service provider MPLS links to interconnect branches.
  • Currently using redundant OSPF ptp link for connectivity.
  • Problem is intra-area ospf always prefered to bgp injected inter-area or external routes.
  • Provider could could accept OSPF into PE and use ospf-Sham to present routes as intra-area.
• 2nd Option GRE over mpls links
