ospf router database
by Ed Rahn 25 Jul '15

Can someone point me in the direction of an overview of ospf? I would like to learn about router databases, how to setup a configuration file, and how to access the information contained in their data packet. thanks Ed

BGP rejected by protocol
by Chip Marshall 21 Jul '15

21 Jul '15

Hello, I'm attempting to use BIRD to redistribute routes from a couple of interesting BGP feed services (Cymru bogons and UTRS) to a bunch of our edge routers, but I'm hitting an issue where BIRD isn't exporting the routes to our edge, every prefix is getting a "rejected by protocol" message in the log. bird6: edge1 < rejected by protocol 2407:dc20::/27 via [removed] on eth0 Here's a copy of my config with sensitive bits removed: https://gist.github.com/2bithacker/6561aa4484507c8f2d9d I think the problem might be related to talking to some peers from one AS and others from an internal AS, but I've tried changing them all to the same AS and it didn't help. Any pointers would be appreciated. I just wish "rejected by protocol" would provide a bit more detail on why it was rejected. -- Chip Marshall <chip(a)2bithacker.net> http://2bithacker.net/

listen address bug
by bird＠unicycle.net 20 Jul '15

20 Jul '15

Hi, I've been debugging a bird6.conf (doing two ASN's) for almost two days, finding each time only one half working, and so being convinced it should work. So finaly I could made a clear conclusion: table as5; table as6; # router id 1.2.3.68; # # mysterious failure: #listen bgp address 2001::1a port 179; #listen bgp address 2001::2a port 179; # this works fine: listen bgp address 2001::2a port 179; listen bgp address 2001::1a port 179; # 8< ----- So by these I'd like to report. -- Leo

OSPF and mass route deletion
by Andrew 19 Jul '15

19 Jul '15

When routes are deleted (for ex., terminating a lot of PPP tunnels for some reason in same time), it seems like each removed route is sent into separate OSPF packet that causes troubles with OSPF in some cases (for ex., there's troubles with old quagga). Is there a possibility to add some rate-limiting (for ex., limit to 10 messages per second), and aggregate separate 'route deleted' messages to one packet?

Route reflector not setting originator_id
by Evelio VILA 17 Jul '15

17 Jul '15

Hello, I have a very simple setup with one rr and one rr client. Im not seeing ORIGINATOR_ID nor CLUSTER_LIST attributes appended to the updates sent to the rr client. Aren't those supposed to be mandatory per RFC 4456 ? filter wr1_import { reject; } filter wr1_export prefix set te_internal; { te_internal = [ 10.0.0.0/8 ]; if (net ~ te_internal) then reject; accept; } protocol bgp bgp_wr1_v4 { description "something"; import filter wr1_import; export filter wr1_export; multihop 2; password "pass"; local as my_as; neighbor X.X.X.X as my_as; source address x.x.x.x; rr client; rr cluster id 1.1.1.1; }

External OSPF route cost metric
by Jigar Mehta 17 Jul '15

17 Jul '15

Hi, Is there a way we can advertise external OSPF routes with the actual route cost instead of ospf.metric1 or ospf.metric2. For eg : Route to 5.5.5.0/24 is via protocol1 with cost of 5 Route to 4.4.4.0/24 is via protocol1 with cost of 6 but ospf advertises this external route with metric of 10000. (I know i can change the 10000 in the config) but both the routes will be advertised with the same cost instead of 5 or 6. I have assigned the protocol1 with highest preference but need to also advertise with the actual cost. Is it possible to use the filter and replace the ospf metric with the above route metric ? Thanks, JM
