Hi

You have two pairs of routing tables (master4/6 and mtab4/6), BGP is
connected to both (regular to master4/6 and 3107 to mtab4/6). But only
the master4/6 is connected by kernel protocol to the real kernel routing
table.

You probably do not need regular BGP, only RFC 3107 (there are no routes
in master4/6 other than from Direct protocol). So you should:

Remove additional routing tables:

  ipv4 table mtab4;
  ipv6 table mtab6;

Remove 'ipv4' block in BGP, keep only 'ipv4 mpls' block (RFC 3107 routes)

Remove 'table mtab4' from 'ipv4 mpls' block.
