GLBP EIGRP Scenario

    I posted a couple of weeks ago about EIGRP over MPLS. The scenario
    that I was having problems with was balancing the traffic across two
    T1s attached to two Cisco 3845s. We have HSRP for redundancy, but on a
    suggestion from this group, I am pursuing configuring GLBP instead of
    HSRP. However, now, I am wondering if I should setup GLBP on both
    sides of the routers, i.e. both into the MPLS cloud to which all
    branches are attached and into the LAN. Below are the two setups that
    I am considering (best viewed in fixed-width font). I am using EIGRP
    for routing traffic across the MPLS cloud. My question is this, how
    will EIGRP broadcast the route back to these two routers to our branch
    offices? If I setup GLBP on both sides of the two routers, will I be
    balancing traffic more efficiently than EIGRP can do on the MPLS
    links? Thanks.

    If anyone could give me a moment's time to clear up this question, I
    would be most appreciative. Thanks.
