Fault fltIpv6NexthopOperStDown
                

Rule ID:1616

Explanation:
This fault occurs when the operational state of the next hop is changed to down due to various config or operational reasons

Recommended Action:
To recover from this fault, try the following actions

1. For rt-unreachable fault check if the nexthop can be resolved by oter routes and resolved nexthop is reachable via a directly connected subnet
2. For vrf-down fault check the operational state of nexthop vrf and ensure it is up
3. For link-local-pfx fault check if the route pfx is a link local pfx, if yes change to a non link local pfx
4. For invalid-pfx-mask fault check if the route pfx and mask combination is a invalid, if yes change to a valid pfx mask combination
5. For invalid-nh, invalid-nh-mask fault(s) check if the next hop pfx or/and mask combination is invalid, if yes change to a valid next hop pfx and mask
6. For local-nh fault check if the route pfx is a local address, if yes chage it to a non local address
7. For mcast-nh fault check if the next hop is a multicast address, if yes change ot to a non mcast address
8. For lo-addr fault check if the route pfx is a loopback address if yes change it to a non loopback address
9. For max-nh-exceeded fault check if the maximum number of nexthops (16) per route limit is reached, if yes delete some next hop(s) configured for the route
