Distribute-list in

The distribute-list in attach point within OSPF allows use of route policies to filter OSPF prefixes. The
distribute-list in route-policy can be configured at OSPF instance, area, and interface levels. The route-policy
used in the distribute-list in command supports match statements, "destination" and "rib-metric". The "set"
commands are not supported in the route-policy.
These are examples of valid route-policies for "distribute-list in":
route-policy DEST
if destination in (10.10.10.10/32) then
drop
else
pass
endif
end-policy
route-policy METRIC
if rib-metric ge 10 and rib-metric le 19 then
drop
else
pass
endif
end-policy
prefix-set R-PFX
10.10.10.30
end-set
route-policy R-SET
if destination in R-PFX and rib-metric le 20 then
pass
else
drop
endif
end-policy
