Instead i would rather aggregate in RR . Remote traffic will work fine since lfib will nicely deaggregate traffic and forward is to proper /32. In case you can't live without aggregating on some PE (and without mantaing on pe /32 in several vrf's via rt import/export on PE) you can probably solve that by some smart inter vrf static routes ( it will only work when next-hop is point-to-point interface). regards Piotr Marecki ------- The MPLS-OPS Mailing List Subscribe/Unsubscribe: http://www.mplsrc.com/mplsops.shtml Archive: http://www.mplsrc.com/mpls-ops_archive.shtml
