For MVPN, routes of SAFI 128 or 129 are UMH-eligible routes. For GTM, routes of SAFI 1, SAFI 4, or SAFI 2 are UMH-eligible routes. Imported routes of SAFI 2 in the global table are UMH-eligible routes; otherwise, routes of SAFI 1 or SAFI 4 are considered UMH-eligible routes. For UMH determination, SAFI 1 and SAFI 4 routes containing the same IP prefix in their respective NLRI fields are considered by the BGP best-path selection process to be comparable.
UMH-eligible routes that have a SAFI of 1, 2, or 4 carry both the VRF Route Import EC and the Source AS EC. These ECs are automatically configured for GTM.
