  1. Add "bgp bestpath peer-type multipath-relax" to frr 

    This new BGP configuration is akin to "bgp bestpath aspath multipath-relax".
When applied, paths learned from different peer types will be eligible
to be considered for multipath (ECMP). Paths from all of eBGP, iBGP, and
confederation peers may be included in a multipath group if they are
otherwise equal cost.

When such a multipath group is created, it is not desirable for
iBGP nexthops to be discarded from the FIB because they are not directly
connected. So when publishing the nexthop group to zebra, bgpd will allow
recursive resolution, but only when there are iBGP-learned paths in the
group.
