We have a PPPoE server running on a RB433 with 3.30. It is linked up in a ring topology via eth0 and wlan1. The pppoe server runs on wlan2. Now we are running OSPF and it is working great. Unfortunately all OSPF updates seem to be going to all the PPPoE client connections. Now I know you can mark an interface as “passive” which would solve this problem. Marking wlan2 as passive doesn’t work (which I didn’t think should work). Looks like we can mark “passive” on all the pppoe dynamic interfaces; but that is not practical. Is there a way to mark all links created by a PPPoE server as “passive”?
Also I tried directly filter OSPF with this firewall rule:
ip firewall filter
add action=drop chain=forward comment=“Drop all multicast to clients”
disabled=no dst-address=10.200.1.0/24 protocol=ospf
The PPPoE pool is subnet 10.200.1.0/24. After adding this rule, we are still seeing OSPF traffic on the PPPoE interfaces.
Anyone know a solution? I would really like to be able to make the entire PPPoE server passive. But I am open to anything at this point.
