This read-only IpAddress is the forwarding address to which traffic for this externally redistributed destination should be sent, or 0.0.0.0 to indicate traffic should instead be forwarded to the LSA's originating ASBR. An admin troubleshooting a black-holed external route checks whether this address points to a next-hop that is actually still reachable. For example, if this field shows a router that has since been decommissioned, traffic to that external network would be forwarded to a dead next-hop instead of reaching the ASBR.
