This document describes a next hop field in the route redistribution profile works in conjunction with interface and destination addresses.
In a route redistribution profile, select the source type (for example, static, connect) desired to redistribute. There are three more optional filters that can be configured (interface, destination and next hop). If one or more interfaces/destination/next-hop is configured, then static routes(in this example) which have those interfaces "AND" those destination addresses "AND" those next hops will only be used for redistribution.
For example, static routes are being redistributed. Interfaces, destination and next hop are configured, as shown below:
Logic to filter the routes will be like this:
(Static routes) AND (eth1/3 or eth1/4) AND (172.16.10.0/24 or 172.16.18.0/25 or 10.10.10.0/24 or 184.108.40.206/24 ) AND (next-hop 192.168.88.2 or next-hop 10.66.24.1).
See the following static routes configured in the VR:
