Monitoring OSPF
by Ruben Laban 09 Sep '11

09 Sep '11

Hi list, I was wondering if there's a sane method to keep a realtime eye on OSPF. More specifically, getting notifications for link/state/topology/etc changes. So far all I could think of is using birdc(6) every x seconds/minutes and comparing the output with the previous run to detect changes. Possibly the (debug) log could be of service here as well, but have not yet looked into that in detail. Any pointers would be welcome. Regards, Ruben Laban

Unsolicited router advertisements
by Alex Bligh 07 Sep '11

07 Sep '11

If I am running bird6 sending IPv6 router advertisements, is there a way I can persuade bird (without shutting it down and restarting it) to send unsolicited router advertisements, as per RFC2461 s6.2.4? Can I do this through a birdc complete restart of the ra protocol or similar? Or will that maintain timers? -- Alex Bligh

Hi folks, maybe the following is of interest for you: We are happy to announce the first public, open-source reference implementation of the RPKI/RTR client. The library is implemented in C and based on draft-ietf-sidr-rpki-rtr-16, draft-ietf-sidr-pfx-validate-02. The current release implements RTR-Sockets, which support SSH and unprotected TCP as transport layer. Automatic failover for multiple RTR servers is not yet implemented, but planned for the next release. The RTRlib 0.1 beta version and its documentation is available at: * http://rpki.realmv6.org/ Any feedback is highly appreciated! Cheers matthias -- Matthias Waehlisch .

Hi! I can't remember if I read it here on the list but does carp and bird work under freebsd? As of now, even if a carp interface is in backup mode, bird announce that prefix over ospf, which I don't want... -- //fredan

several bgp/attrs.c questions
by Alexander V. Chernikov 02 Sep '11

02 Sep '11

Hello list! I've got several questions after some attribute code digging: 1) We're calling custom formatting function bgp_get_attr() with wrong lentgh (attribute name is not taken into account). This probably never will cause buffer overflow, but still: if we're passing buffer length it should be real length. Possible simple fix is in bgp_get_attr.diff 2) We know that either no extended attributes (route withdraw) or a pack (ORIGIN, AS_PATH, NEXTHOP) of mandatory attributes (and possibly some other) are passed within BGP UPDATE message. However we're allocating ea_list with single extended attribute on every BGP attribute we parse in bgp_decode_attr(). Maybe we can pre-allocate more than one attribute in ea_list ? Example implementation can be found in attached bgp_attr_ea.diff -- Alexander V. Chernikov Yandex NOC
