OSPFv2 in a VRF, FRR 6.0.2 on Ubuntu 18.10

Hi folks, I'm trying to set up a lab environment to test some OSPF stuff. I installed the FRR 6.0.2-0~ubuntu18.04.1 package on top of Ubuntu 18.10. I elected to leave my management interface (ens3) in the default VRF and put the others in a VRF called "WAN", shown as item #10 below: $ ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:68:bb:72 brd ff:ff:ff:ff:ff:ff 3: ens9: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:ed:f8:ad brd ff:ff:ff:ff:ff:ff 4: ens10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:07:11:c7 brd ff:ff:ff:ff:ff:ff 5: ens11: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:6e:51:76 brd ff:ff:ff:ff:ff:ff 6: ens12: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:bf:5d:f3 brd ff:ff:ff:ff:ff:ff 7: ens13: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:f5:24:55 brd ff:ff:ff:ff:ff:ff 8: ens14: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:d3:1d:30 brd ff:ff:ff:ff:ff:ff 9: ens15: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master WAN state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:e3:cf:dd brd ff:ff:ff:ff:ff:ff 10: WAN: <NOARP,MASTER,UP,LOWER_UP> mtu 65536 qdisc noqueue state UP mode DEFAULT group default qlen 1000 link/ether 06:6a:07:90:27:3a brd ff:ff:ff:ff:ff:ff "ip route" correctly shows only the connected subnet route for the management net and a default: $ ip route default via 192.168.42.1 dev ens3 proto static 192.168.42.0/24 dev ens3 proto kernel scope link src 192.168.42.153 And the other connected routes in the VRF: $ ip route show vrf WAN unreachable default metric 4278198272 172.16.1.0/24 dev ens9 proto kernel scope link src 172.16.1.1 172.17.1.0/24 dev ens14 proto kernel scope link src 172.17.1.1 192.0.2.0/24 dev ens10 proto kernel scope link src 192.0.2.1 198.51.100.0/24 dev ens11 proto kernel scope link src 198.51.100.1 203.0.113.0/24 dev ens12 proto kernel scope link src 203.0.113.1 What I see inside vtysh matches: $ ip route show vrf WAN unreachable default metric 4278198272 172.16.1.0/24 dev ens9 proto kernel scope link src 172.16.1.1 172.17.1.0/24 dev ens14 proto kernel scope link src 172.17.1.1 192.0.2.0/24 dev ens10 proto kernel scope link src 192.0.2.1 198.51.100.0/24 dev ens11 proto kernel scope link src 198.51.100.1 203.0.113.0/24 dev ens12 proto kernel scope link src 203.0.113.1 router# sho ip ro vrf WAN Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP, F - PBR, > - selected route, * - FIB route VRF WAN: K * 0.0.0.0/0 [255/8192] unreachable (ICMP unreachable), 04:04:10 C>* 172.16.1.0/24 is directly connected, ens9, 04:04:10 C>* 172.17.1.0/24 is directly connected, ens14, 04:04:10 C>* 192.0.2.0/24 is directly connected, ens10, 04:04:10 C>* 198.51.100.0/24 is directly connected, ens11, 04:04:10 C>* 203.0.113.0/24 is directly connected, ens12, 04:04:10 So far so good. Now I enabled ospfd in /etc/frr/daemons and restarted FRR. The ospfd process is running: $ ps -ef|grep frr root 2045 1 0 13:31 ? 00:00:02 /usr/lib/frr/watchfrr -d -r /usr/lib/frr/watchfrr.sh restart %s -s /usr/lib/frr/watchfrr.sh start %s -k /usr/lib/frr/watchfrr.sh stop %s zebra ospfd staticd frr 2059 1 0 13:31 ? 00:00:00 /usr/lib/frr/zebra -d -A 127.0.0.1 -s 90000000 frr 2064 1 0 13:31 ? 00:00:01 /usr/lib/frr/ospfd -d -A 127.0.0.1 frr 2069 1 0 13:31 ? 00:00:00 /usr/lib/frr/staticd -d -A 127.0.0.1 Then I put in some seemingly basic OSPF config shown below. Yes, I really only want to speak OSPF on one of the interfaces (ens14) for now. router# sho run Building configuration...

7.0 release
by David Lamparter 13 Mar '19

13 Mar '19

Hi all, I'm very happy to announce we have released version 7.0 of FRRouting! [https://github.com/FRRouting/frr/releases] There are some major changes in this release, specifically libyang [https://github.com/CESNET/libyang] is now a hard requirement to build and run FRRouting. Here's the full list of major changes from 6.0.x to 7.0: - YANG data modeling & NETCONF support has arrived for the following daemons: - ripd - ripngd - isisd Note that this uses FRR-specific models and may still be subject to some changes. Feedback is strongly appreciated! - Error Codes / Categories are now added to log messages. They are printed as [EC 99999999999] on log messages and identify classes of errors. The library, bgpd, ospfd and zebra have been properly extended to categorize errors while the other daemons have somewhat more rudimentary cateogries. - "configure terminal" in the CLI is no longer an exclusive state on any daemon, i.e. multiple users can edit the configuration at the same time in all daemons. This was previously already the case for zebra and isisd. - BGP enhancements: - EVPN Duplicate Address Detection - EVPN route servers - EVPN extended mobility - Global IPv6 addresses can be used for RFC5549 (v4-over-v6) nexthops - Flowspec protocol support has been significantly extended. (Note that OS integration is still very incomplete.) - Add-Path IDs are now reused on transmission when possible - Aggregates now properly aggregate extended and large community attributes - IS-IS: - BFD support has been added - triggered hellos have been implemented - new daemon: OpenFabric (a datacenter variant of IS-IS - cf. https://datatracker.ietf.org/doc/draft-white-openfabric/) - Zebra's kernel/dataplane interface is undergoing a rewrite and parts have been moved into a separate thread with a more extensible architecture. Work on this project is ongoing. - staticd now supports onlink nexthops for static routes - sharpd now supports nexthop groups for route installs - many bugs were fixed, also including quite a few overdue documentation improvements. This also includes CVE-2017-3224 which is a low-severity low-impact OSPF vulnerability (as evident by the 2017 date.) Important packaging and build related changes: - libyang is now required to build and run FRRouting. Version 0.16.74 or newer (e.g. 0.16-r3 which is 0.16.105) is strongly recommended. Older versions will create additional hazards at both build and runtime because an extension module needs to be installed. Support for libyang versions before 0.16.74 will be removed in the next non-stable FRRouting version. - when using libyang before 0.16.74, make sure to specify the "--with-libyang-pluginsdir=/usr/lib/frr/libyang_plugins" option (change path to fit system) - Debian packaging has been completely overhauled (matches the changes in 6.0.2.) If you are creating derivative Debian packages, updates will be necessary. - RPKI and SNMP are now separate packages that can be installed additionally. There are no longer distinct "RPKI" and "no RPKI" versions of FRRouting on Debian. - Debian packages are now provided in a repository at: https://deb.frrouting.org/ - Snapcraft packaging has been updated to match. - There is a new "--enable-static-bin" option to link libfrr statically into FRR binaries. This is the only supported way of doing any static linking of FRR. ("--disable-shared" is NOT supported.) - all daemons now properly complete their startup before allowing their parent to exit when the -d daemonization option is used. This should remove the need for any "sleep" calls or start retrying in init scripts. - some minor non-reproducibility issues were fixed. FRRouting should now always build reproducibly. - the topotests system that was previously maintained separately is now shipped as part of the FRR source under tests/topotests. As you can see this is quite a changelog and I'd like to thank everyone who contributed to this release. It has been a very productive 6 months! Cheers, -David
