Unfortunately, some MPLS implementations do not support the ability to forward packets received on an egress LSP to their OSPF router ID and/or BGP next hop address.
If your MPLS network includes equipment that does not support this type of IP forwarding, you can use configuration commands to explicitly control the use of calculated LSP next hops.
Note
You can enable the use of LSP next hops, or you can enable DHCP/BOOTP relay. The software does not support both features at the same time.These commands enable and disable the calculation of LSP next hops by OSPF:
These commands enable and disable the calculation of LSP next hops by BGP:
