I have seen a deployment, where services were deployed via some centralized provisioning system. Part of the service provisioning was to adjust the LDP export policy on ABR, since LDP DU was used (some access PEs didn’t supported LDP DoD in that deployment). So, if you have some devices without LDP DoD support, your only choice is LDP DU + policies :-). > >> On Mon, Jul 30, 2018, 11:15 James Bensley <jwbens...@gmail.com> wrote: >>> unless we create horrible per-LDP >>> neighbour policies on the agg node that only allow the labels for the >>> exact loopbacks that access node needs to reach. > > Cheers, > James. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
