OSPF Layer 2 MPLS

  • 1.  OSPF Layer 2 MPLS

    Posted May 07, 2015 03:11 PM

    I'm putting together a full switch upgrade project for a client of mine.

     

    They have 10 locations connected via a Layer 2 MPLS circuit. 

    The L2 MPLS is not segemented between the schools but is just a single vlan connecting all the locations together. 

    Each routing switch at each location has an IP address in a single /24 subnet. 

    Currently, routing is being done using EIGRP.

     

    For the locations with chassis I'm recommedning the 5400r.

    For the locations with a fixed port switch I'm recommedning the Procurve 3800 switch.

    Routing would be migrated to OSPF.

     

    I've been reviewing the Multicast & Routing guides and discovered that these do not support NBMA.  I was also told by my HP SE that they also do not support P2MP.  All the examples I've found are either just 2 switches connected via OSPF or multiple switches but a separate transit vlan between them.  Basically all P2P examples.

     

    The question that I can't find an answer for is what would happen if I setup OSPF with these devices?  Would every switch discover every other switch and create a full mesh?  While not optimal, this would work and basically mirror what they have now.

     

    Thanks for any help!
