2019-08-01Nest: VRF of protocol can be explicitly specified as 'default'Ondrej Zajicek (work)
Protocol can have specified VRF, in such case it is restricted to a set of ifaces associated with the VRF, otherwise it can use all interfaces. The patch allows to specify VRF as 'default', in which case it is restricted to a set of iface not associated with any VRF.

2017-09-19BGP: Shutdown communication (RFC 8203)Ondrej Zajicek (work)
The patch implements BGP Administrative Shutdown Communication (RFC 8203) allowing BGP operators to pass messages related to BGP session administrative shutdown/restart. It handles both transmit and receive of shutdown messages. Messages are logged and may be displayed by show protocol all command. Thanks to Job Snijders for the basic patch.
2017-09-06Basic VRF supportOndrej Zajicek (work)
Add basic VRF (virtual routing and forwarding) support. Protocols can be associated with VRFs, such protocols will be restricted to interfaces assigned to the VRF (as reported by Linux kernel) and will use sockets bound to the VRF. E.g., different multihop BGP instances can use diffent kernel routing tables to handle BGP TCP connections. The VRF support is preliminary, currently there are several limitations: - Recent Linux kernels (4.11) do not handle correctly sockets bound to interaces that are part of VRF, so most protocols other than multihop BGP do not work. This will be fixed by future kernel versions. - Neighbor cache ignores VRFs. Breaks config with the same prefix on local interfaces in different VRFs. Not much problem as single hop protocols do not work anyways. - Olock code ignores VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. - Incoming BGP connections are not dispatched according to VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. Perhaps we would need some kernel API to read VRF of incoming connection? Or probably use multiple listening sockets in int-new branch. - We should handle master VRF interface up/down events and perhaps disable associated protocols when VRF goes down. Or at least disable associated interfaces. - Also we should check if the master iface is really VRF iface and not some other kind of master iface. - BFD session request dispatch should be aware of VRFs. - Perhaps kernel protocol should read default kernel table ID from VRF iface so it is not necessary to configure it. - Perhaps we should have per-VRF default table.

Thanks to Aleksey Berezin for the bugreport.
2014-03-20BGP graceful restart support.Ondrej Zajicek
Also significant core protocol state changes needed for that, global graceful restart recovery state and kernel proto support for recovery.
2013-09-26Fixes build issues without BGP.Ondrej Zajicek
Thanks to Sergey Popovich for the patch.
2013-07-25Implements eval command and minor CLI cleanups.Ondrej Zajicek
Implemented eval command can be used to evaluate expressions. The patch also documents echo command and allows to use log classes instead of integer as a mask for echo.
2013-06-24Better packet priority and traffic class handling.Ondrej Zajicek
Implements support for IPv6 traffic class, sets higher priority for OSPF and RIP outgoing packets by default and allows to configure ToS/DS/TClass IP header field and the local priority of outgoing packets.
2013-02-25Default rounting table for 'show route export/preexport/protocol' is the one ↵Ondrej Filip
related to a respective protocol.
2013-02-14I still believe that 0 == NULL, however this patch will make Santiago happy. :-)Ondrej Filip
2013-02-10Route limits can be disabled - this makes sense for protocol templatesOndrej Filip
2013-01-10Separate import and receive limits.Ondrej Zajicek
They have different behavior w.r.t. filtered routes that are kept.
2012-12-27Implements interface masks for choosing router id.Ondrej Zajicek
Router ID could be automatically determined based of subset of ifaces/addresses specified by 'router id from' option. The patch also does some minor changes related to router ID reconfiguration. Thanks to Alexander V. Chernikov for most of the work.
2012-11-15Changes 'rejected' to 'filtered' in one of the last patches.Ondrej Zajicek
2012-11-10Allows rejected routes to be kept and examined.Ondrej Zajicek
When 'import keep rejected' protocol option is activated, routes rejected by the import filter are kept in the routing table, but they are hidden and not propagated to other protocols. It is possible to examine them using 'show route rejected'.
