Agregator protocol

[Luk]

Hi,

I'm   trying   to   use  aggregator  protocol  (patch  from  Alexander
Chernikov).  Can  someone explain if I can use this patch to aggregate
routes to upstream providers ? My goal is to not use "route x.x.x.x/xy
reject;"  syntax  to  announce  routes to the internet, but rather use
aggregation,  which  will  be  used  only if there will be one or more
more-specific-route within particular prefix from iBGP session.

Regards,
 Luk

MTU mismatch with nbr

[Derek Andrew]

We are running BIRD and BIRD6 to manage our BFD and OSPF relationship on
our DNS servers.

We moved the DNS servers onto a Fortigate firewall. I was able to get the
BIRD daemon running, but BIRD6 is complaining about an MTU mismatch with
the neighbour.

Is there any way to tell BIRD to ignore the MTU? The OSPF status is showing
the neighbour is in the Exchange state.

Thanks.

Re: TCP md5 authentication failures for almost on all the server's BGP peering

[Stanislaw]

Hi, 

Don't know if it is still actual for the original poster. 

I've been encountered with it in Centos 6. Actually those messages are
harmless since TCP just resends the packet with a correct checksum. 

It seems to be a rhel6 kernel bug to me, not BIRDs. Moving to the recent
version didn't help, but to Centos 7 did.

Hi,

I can recommend https://dn42.eu/howto/Bird. There are some BIRD example 
configuration snippets. :)
You can also have a look in here -->
