Juniper BGP - CONFIGURATION GUIDE V 11.1.X Configuration Manual page 525

When it is received from other type of peers, the indirect next hop is
reachable if an entry exists in the IP routing table that resolves this
indirect next-hop address.
For VPN labeled routes in a VRF, the following rules apply:
When it is received in a core VRF from a remote multihop IBGP or EBGP
VPN peer, the indirect next hop is reachable if an entry exists in the IP
tunnel routing table that resolves the next-hop address.
When it is received in a core VRF from a nonmultihop peer, the indirect
next hop is reachable if the MPLS major interface next to the peer IP
interface exists and is operationally up.
Metric Metric of the BGP indirect next hop
Number of direct next-hops Number of the equal-cost legs of direct next
hops that this indirect next hop resolves to
Direct next-hop IP interface and next-hop IP address that resolve the BGP
indirect next hop; the direct next hop can also be an IP indirect next hop or
an MPLS indirect next hop when chains of next hops are in use
Reference count Number of label mappings of BGP routes that use this
next hop
