But I don't see these routes in a bird

It is necessary to declare these routes to OSPF neighbors.

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
Error after I add RTS_OSPF_EXT in filter

Why I receive error?

Ok.
I have changed filter. Now he is

Error again.
I have checked all from possible values: RTS_DUMMY,
RTS_STATIC, RTS_INHERIT, RTS_DEVICE, RTS_STATIC_DEVICE, RTS_REDIRECT,
RTS_RIP, RTS_OSPF, RTS_OSPF_IA, RTS_OSPF_EXT, RTS_BGP, RTS_PIPE.
Only RTS_OSPF_EXT don't work.
PS
RTS_OSPF_INT - It is my carelessness

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.

If during review of the table of routing by ' show route ' command to interrupt output having pressed a key ' q ', bird long thinks. I wait for appearance ' bird ' approximately 7 seconds. Such delay on Cisco routers is not present. With such delay it is very inconvenient to work with birdc. 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.
