Comments on: OSPF default route in JUNOS https://backreference.org/2009/12/04/ospf-default-route-in-junos/ Proudly uncool and out of fashion Sat, 05 Jul 2014 18:31:00 +0000 hourly 1 https://wordpress.org/?v=5.8.2 By: waldner https://backreference.org/2009/12/04/ospf-default-route-in-junos/#comment-25104 Sat, 05 Jul 2014 18:31:00 +0000 http://backreference.org/?p=253#comment-25104 In reply to Andrea.

As explained previously in the text, "discard" is used to completely blackhole the traffic. "reject", instead, would send back an ICMP error packet.

in the following case:

generate {
    route 0.0.0.0/0 {
        policy filter-contributors;
        discard;
    }

What "discard" is exactly for?

Thank you,
Andrea

They are way too abstract, their examples don't represent real-world setups, unstructured (and expect you to be a JNCP already or something)...
This was very clear, I got it from the first read!

I see JunOS has a RPM (real-time performance monitoring) feature which looks similar to what IP SLA can do. However, I don't know whether RPM results can be used as criteria for conditional advertisement; but it should be a starting point for further investigation.

Similar to the IPSLA tracking option within Cisco IOS
