Memory consumption has been multiplied by 480 in less than 24 hours.

I guess this is not a normal behavior isn't it ?

Definitely not. I will check that. Could you send an output of
'show route all' cmd ?

BGP configuration HELP

[OSPF] BIRD <> Mikrotik checksum

Hi!
I have a problem with binding bird with mikrotik router os.
The RouterOS says:
Discarding packet: wrong checksum.

In the bird manual we can find
"The RFC says that a router should check the checksum of every LSA to
detect hardware problems. BIRD does not do this to minimalize CPU
utilization."
Does the BIRD send checksum in OSPF

That is my OSPF config:
protocol ospf LandtechOSPF {
       tick 2;
        rfc1583compat yes;
        area 0.0.0.0 {
                stub no;
                interface "eth1" {
                        hello 10;
                        retransmit 5;
                        cost 10;
                        transmit delay 5;
                        dead 40;
                        dead count 40;
                        wait 50;
                        type broadcast;
                };
        };
}

Thanks for help!

Checking if bgp_next_hop matches bgp neighbor

Hi,

just wondering what the correct way is to filter if the advertised
bgp_next_hop matches the neighbor address in a filter.

Would

if from != bgp_next_hop then reject;

do the trick, or do I have to define a function as inbound filter and
pass the neighbor address as a parameter?

Thanks,
Peter

Imho this check should do. Would make sense to add this to your list of
checks (martians, prefix length, source ...)

best regards,
Arnold

Yes, this clause is fine and it should do what you're looking for.

Strange. I will check that.

Yes, BIRD sends and checks checksums, it just doesn't repeatedly checks
checksums of LSAs already in LSAdb.

Deleting wildcard bgp communitities in an outbound filter

Hi,

i would like to hide some traffic engineering communities from bgp advertisements to peers.

I'm using Bird 1.2.4 and from what I have read in the Changelog it should be possible to have something
like this in an outbound filter

bgp_community.delete((65000,*));

However, this statement generates a syntax error.

Any hints?

Thanks,
Peter
