Problem:
CCR1 is unable to reach 41.79.23.48/29 subnet via CCR2. I assume MPLS forwarding table should not have 'out-labels' associated for the route to 41.79.23.48/29, as the MPLS label should be popped before forwarding it on to CCR2 (last MPLS router before customer CPE). I would have expected 'mpls forwarding-table print detail where destination in 41.79.23.48/29' to show the following:
0 L in-label=2590 out-labels="" interface=seacom-vlan21-vlan210 nexthop=198.19.12.54 destination=41.79.23.48/29
PS: Loading '/mpls ldp accept-filter add accept=no prefix=41.79.23.48/29' restores connectivity but obviously disables MPLS for the subnet.
