RE: How redistribute routes from kernel table to OSPF protocol?
Problem solved. I find it
Kernel protocol with learn may generate these routes, but there is an
exception for device routes in sysdep/linux/netlink/netlink.c:848 :
/*
* In Linux IPv6, 'native' device routes have proto
* RTPROT_BOOT and not RTPROT_KERNEL (which they have in
* IPv4 and which is expected). We cannot distinguish
* 'native' and user defined device routes, so we ignore all
* such device routes and for consistency, we have the same
* behavior in IPv4. Anyway, users should use RTPROT_STATIC
* for their 'alien' routes.
*/
if (i->rtm_protocol == RTPROT_BOOT)
src = KRT_SRC_KERNEL;
If you remove these two lines and recompile BIRD, you could probably be able
to import device routes.

scan time of protocol kernel
Hi, Now 'scan time' set to 60 sec. The bird load system up to 100% during 10-12 sec every 60 sec. What circumstances to take into consideration that it is correct to set 'scan time' of protocol kernel? If I do not add paths with linux the console, whether I can delete 'scan time' from the protocol kernel? Vladislav Grishin

Because the values are RTS_OSPF, RTS_OSPF_IA and RTS_OSPF_EXT,
not RTS_OSPF_INT.
RTS_OSPF is for plain, intra-area OSPF routes.

Whether are compatible Cisco IOS and BIRD at usage OSPF MD5 of authentification?
I have of two bird (bird1 and bird2 ) and two Cisco devices (cisco1 and

Whether are compatible Cisco IOS and BIRD at usage OSPF MD5 of
authentification?

There is a delay because scrolling and interrupting of output is implemented solely in birdc and bird always generates full output that takes a time. OTOH, on testing masine with Pentium 2, 2 Ghz with full BGP feed (320k routes) i got a delay ~ 1.5 s. Usually this is not a problem because users anyway have to use filtered show route cmd to cope with many routes. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

If there are more routes to the same destination, only the best route is considered for export. If the best route is filtered, then no route is exported. If you want to export one default route to the OSPF and a different one to the downstream BGP, you have to use two routing tables and a pipe, for example one (master) routing table for upstream BGP and OSPF and another table for downstream BGP and a static protocol with a default route. And a pipe that forwards routes from master to the secondary table, but does not forward default from secondary to the primary table. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
Why filter not work for two cases?
My network.
Bird is used as border router on the standalone server.
I have a two upstream ISPs from which I accept full view + default route
over eBGP.
I have a one downstream ISP to which I announce full view + default route.
Into my AS a IGP protocol is OSPF. The L3 switch Cisco 3550 is used on a
network.
Bird IP is 10.10.1.2, Cisco 3550 IP is 10.10.1.3.
To BGP downstream I plan to announce a default route which is exported from
the bird static protocol, for stability.
For OSPF neighbors I plan to announce a default route which is received from
the upstream ISPs, since for each operator in the future there will be a
server.
Now the default route in routing table is imported only from upstreams,
route to 0.0.0.0/0 network is not present in static protocol of bird.

Why the default route is not exported to OSPF protocol from bird routing
table after adding
route 0.0.0.0/0 via "lo";
in bird.config of static protocol?
Why filter export_default_route_from_bgp_to_ospf does not work for two
cases?

Hi Vladislav, this clause: net ~ 1.0.0.0/8 means "NET is subnetwork (of network itself) of 1.0.0.0/8". So networks like 1.1.0.0/16 or 1.0.0.0/8 are accepted by the filter. But this clause: net ~ [ 1.0.0.0/8 ] means "NET is a member of prefix list (prefix list is in []) with a single member 1.0.0.0/8. So basically only 1.0.0.0/8 is matched. That's why export_default_1 accepts just default route (0.0.0.0/0) and export_default_2 accepts default route and all subnetworks. So your filters export_net_1 and export_net_2 are not equal. The filter export_net_2 would e.g. accept route 12.12.12.13/32, but that is probably not in your routing table. "net ~ [ 1.0.0.0/8]" is equal with "net = 1.0.0.0/8" Ondrej F. > > Vladislav Grishin >

Why filters export_net_1 and export_net_2 work equally, and/but filters
export_default_1 and export_default_1 on a miscellaneous?
Why the filter export_default_2 "does not work" also as the filter
export_net_2 works?

bird routing table despite the fact that what 1.1.1.0/24 and 2.2.2.0/24 are
