Filter OSPF inbound route

[farsoft]

Hello,

I've got an OS6860 switch in a OSPF topology. A neighbour is advertising to it a route that I don't want to be load in the routing table but I can't find how to filter it.

In Cisco devices we can use a prefix and an inbound distribute-list to decide which received OSPF routes are allowed or denied.

Example:

distribute-list prefix prefix_name in

Do you know if there is an equivalent in Alcatel, please?

Thank you very much.

Regards.

Easiest way is that the ospf neighbour isn't senting this unwanted routes. For this you need to create (at the neighbour) a route-map with your excluded route (with lower sequ-number and action deny). In the same route-map with higher sequence-number you "permit" all routes (0.0.0.0/0). This route-map you use for redistribution (f.e. static into ospf).
But if you do not want to use always received routes I have only one idea. Static routes have a higher precedence than ospf routes. So you can create your own static routes - maybe as blackhole route "ip static-route x.x.x.x/x gateway NULL metric 1".
Also you work with different areas and can use one router as ABR (f.e. in a different VRF of one of your switches). There you can also use the first example (route-map) to forward only specific routes into the NSSA or stub area.
