Hi Randy, 
I think for the basic requirements, the deployed LLDP will suffice. I guess it depends on the other IEEE 802 TLVs that need to be sent in each periodic advertisement. 
Thanks,
Acee

    ace,
    
    so i have been sitting on this for a month, trying to think how to be
    simple about this
    
    draft-ymbk-lsvr-l3dl-ulpc was not directly intended for this.  it is a
    layer two protocol to go with l3dl.  i think we probably want a layer
    three protocol, though there are discovery issues.  btw, for loopback
    peering, pass the forwarding setup in the attribute list.  though you
    can discover that loopbacks are present, you re not going to discover
    that loopback bgp peering is desired, and over which loopbacks (zing).
    
    unfortunately draft-acee-idr-lldp-peer-discovery will need lldpv2 to get
    reasonable pdus.  i am trying to help the lldpv2 work over in 802.1.  i
    do not understand ieee processing pacing.  but if it took idr eight
    yesas to change a constant 4,096 to 64k, i suspect i may not have the
    patience for ieee (actually i was an ieee tag chair back in the early
    '80s) :)
    
    so i think we have some work to do.  but that's why we get the big bucks
    or won.  settling the requirement parameters and limits up front is
    important.  i see the extant drafts as examples and a source for ideas,
    not competitors for a solution.
