Combination of DPC and full route is usually not a good idea, considering the size of the full route these days.
Best thing you can do is of course replacing them with MPC cards. If not possible I think FIB Localization might do the trick for you - must say I havn't tried it myself, just make sure the routers uplinks are on the MPC before you try it https://www.juniper.net/documentation/en_US/junos/topics/topic-map/fib-localization.html Daniel On Mon, Apr 20, 2020, 21:29 Dario Amaya <darioamay...@gmail.com> wrote: > Hello, > > We're running a couple of MX960 in our datacenter, carrying a full > table in BGP and running full MPLS services, fast-reroute/RSVP/LDP > etc. There are two LSP's in full mesh with two other routers.
