Multivendor Support for Calculated LSPs

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.

The following commands enable and disable all use of LSP next hops. No IP traffic is routed over an LSP when mpls-next-hop IP routing capability is disabled.
  • enable iproute mpls-next-hop
  • disable iproute mpls-next-hop

    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:
