Dear recipients,
I have been using OpenBGP for a while with OpenBSD - And I am very satisfied
with the performance and amazed by the ease of configuration.
My BGPD is configured against a Danish ISP called TDC - And we were previously
configured to receive a full routing table.
However a few months ago I ran into an issue where my BGPD stopped working
properly.
It appeared the BGPD kept receiving the routing tables, and then start all
over.
Looking into the log files, it appeared BGPD received a certain route in the
routing table, and then grumbled about the prefix, apparently for some reason
the result was BGPD kept reloading when it reached this route. The result was
of course my network was down.
As TDC (My ISP) couldn't resolve which route that caused this issue (They told
me: "That's what happened when you use third party software", so no help
there...), we agreed that my connection would be set to Default candidate,
instead of receiving a full routing table.
So now I have configured a static route to forward all my traffic to this
route. However this is not the result I wanted, as I am about to have one more
connection, so I have 2 connections outbound.
But the automatic failover switch / load balancing won't work, as long as I
have my static route.
This is why I want to go back to receiving a full routing table.
Is there any way of configuring BGPD to ignore a specific route in case of
"corrupted" prefix, so this won't happened again?
I hope that some of you have an answer for this...
Here you can see my bgpd.conf:
AS 0000
router-id 000.000.000.000
network 000.000.000.00/00
neighbor 000.000.000.000 {
remote-as 0000
descr TDC
local-address 000.000.000.000
