I have been working with the netlink and router plugins, which I was able to build from the 18.07 tree via the instructions in vppsb/router.
(NB: trying to build from anything more recent, e.g. 18.10 or 19.01 breaks, with no obvious easy resolution). When running with these plugins, connected with an open source router (bird version 1.6.4 or 2.02) and with a very small routing table, it works really really well. (I was able to run roughly line-rate 10g even with small packets, and when using a second host with vpp and the span->pg->pcap to /tmp, didn't lose any data.) However, when trying to load up the routing table, things went sideways, and it seems to be something netlink-related.(This was using BGP to feed in 3 copies of the full routing table, each copy of which is about 750K routes.) I was hoping someone could provide good instructions (good == tested and works) on building from a more recent release of VPP to see if it's an issue that has been fixed. If the issue persists and/or looks to be netlink-specific, would anyone be able to look into it? I'm happy to provide logs etc. System is bare metal centos7.5, tons of cores, memory, etc. The first few messages in syslog look like: Nov 27 17:57:30 sj2tldnslab09 bird: Kernel dropped some netlink messages, will resync on next scan. Nov 27 17:57:30 sj2tldnslab09 vnet[127960]: rtnl_process_read:467: rtnetlink recv error (27) []: No buffer space available Nov 27 17:57:30 sj2tldnslab09 vnet[127960]: rtnl_process_read:467: rtnetlink recv error (27) []: No buffer space available After a bunch of similar groups of messages, VPP appears to crash. If this is a known problem or if there's something that needs to be tweaked on the host, any assistance would be greatly appreciated. Brian
