Hi, "advertise ipvX unicast" will also turn on importing routes into the vrf. This setting is actually bidirectional.

Prefix import control from EVPN into VRF
by Iakov Shiriaev 18 Mar '25

18 Mar '25

Hello, I'm looking at EVPN configuration in FRRouting and can't find one particular peace. Under "l2vpn evpn" address family there's an "advertise ipvX unicast" command to start exporting from VRF into EVPN table. This command can also accept a route-map to control what's exported. However, I don't see anything that can control a different direction, i.e. import into VRF. Did I miss it or is it not supported? Yakov Shiryaev, Network engineer Nebius

Hi , I am trying to find a config guide using FRR package for the complete configuration details of EVPN-MPLS and I am unable to find it. Your help is highly appreciated in finding proper documentation about test topology, configuration and any scripts involved.. More specifically about EVPN instance creation , ESID config and the attachment circuit config etc . -Thanks Mahesh ________________________________ Confidentiality Notice: This e-mail is strictly confidential and intended only for the person or entity to which it is addressed.

Re: [FROG] Migration scripts for FRR from Quagga
by Doug Tucker 13 Mar '25

I am under a time crunch now and have to get things going. So with one of my routers, I copied the full bgpd.conf into frr.conf. I am receiving all routes from the remote peer, however, the only outgoing route they are getting from this config is the /24 subnet that the frr router lives in. The other 3 subnets that I have defined are not being propogated. Any ideas what would cause this and how to resolve would be appriciated. I've been searching for a frr.conf sample file on google I could use to compare to mine but coming up empty.

Automatically switch default route to secondary uplink when primary uplink is unavailable
by Thomas Glanzmann 08 Mar '25

08 Mar '25

Hello, I have dark fibre with a static ip and a DSL line behind a NAT box. I would like to have the default route on the dark fibre and switch to the DSL line when the dark fibre is unavailable. I determine if the line is available by ping 1.1.1.1 and 8.8.8.8. I implemented the above in perl, but wonder if I reimplemented the wheel and this is already possible with frr, bird or another piece of software on Linux? Here I don't have BGP available. Find my perl Daemon here (public IPs changed), it runs every minute by cron. https://tg.st/u/genericrouteswitcher.pl Cheers, Thomas

Issue with FRR and ospf6d
by Celsa Sanchez 10 Feb '25

10 Feb '25

Hello everyone, I'm writing to report an issue we're experiencing with FRR and ospf6d. We encountered a problem with a server running ospf6d and attempted to reload the service using the command "clear ipv6 ospf6 process". Unfortunately, this not only shut down the service on that server but also on all routers running the same version and an older version (10.2 and 9.0.1). Servers running version 10.0 remain unaffected. Can anyone offer assistance or insights on this matter? Thanks in advance. Best Regards, Celsa

how to control the metric of routes created by frr?
by Anton Gubar'kov 19 Jan '25

19 Jan '25

Dear fellows, I have trouble finding the particular way of increasing the metric of routes created by frr as a result of the running OSPF. My network is built as follows: The virtual backbone is zerotier 10.243/16. Edge routers are connected to it. Also my laptop is connected to the zerotier backbone (via LTE modem) and runs FRR. Routers run Mikrotik RouterOS and I use OSPF to propagate the routes to 192.168 networks to my Laptop1. 10.243/16: router1 -------- router2 ------- Laptop1 | | | | | | | | 192.168.201/24 192.168.210/24 Everything works fine until I connect my laptop to one of the 192.168 networks via Wifi. 10.243/16: router1 -------- router2 ------- Laptop1 | | | | | | | | | | | | 192.168.201/24 192.168.210/24-----+ By default the metric of the route of the connected Wifi adapter is 600, while the routes that are created by frr have a metric of 20. anton@PF16W6Y2 ~ $ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default router 0.0.0.0 UG 600 0 0 wlan0 10.0.85.2 0.0.0.0 255.255.255.255 UH 0 0 0 outline-tun0 10.243.0.0 0.0.0.0 255.255.0.0 U 0 0 0 ztzlge64hc 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 192.168.201.0 PERV1CAP1.vpn 255.255.255.0 UG 20 0 0 ztzlge64hc 192.168.210.0 0.0.0.0 255.255.255.0 U 600 0 0 wlan0 192.168.210.0 SOV1.vpn 255.255.255.0 UG 20 0 0 ztzlge64hc So when I start to pour a lot of data from my laptop to one of the directly connected servers at 192.168.210/24, the traffic goes to zerotier interface first, then to router2 and decrypted there and only after that reaches the server. The CPU util of the router2 jumps to 100% and the speed goes down. Is there a way to increase the metric of routes via ztzlge64hc interface that are created by frr? Zerotier client doesn't offer to configure the metric of its interface and sets it to 0 always. There is a 5-year old feature request to them for this... The frr config I have is trivial: ! frr version 10.1.1-gentoo frr defaults traditional hostname PF16W6Y2 log file /var/log/frr/ospfd.log log syslog informational no ipv6 forwarding service integrated-vtysh-config ! interface ztzlge64hc ip ospf area 10.243.0.0 10.243.169.159 ip ospf cost 1500 exit ! router ospf ospf router-id 10.243.169.159 log-adjacency-changes exit ! end As you can see I tried to increase the cost of the ztzlge64hc interface and it is correctly reflected in the OSPF routes: PF16W6Y2# show ip ospf route ============ OSPF network routing table ============ N 10.243.0.0/16 [1500] area: 10.243.0.0 directly attached to ztzlge64hc N 192.168.201.0/24 [1501] area: 10.243.0.0 via 10.243.130.110, ztzlge64hc N 192.168.210.0/24 [2500] area: 10.243.0.0 via 10.243.86.42, ztzlge64hc ============ OSPF router routing table ============= R 192.168.201.2 [1500] area: 10.243.0.0, ASBR via 10.243.130.110, ztzlge64hc ============ OSPF external routing table =========== It doesn't affect the kernel route metrics however... Thanks for pointing me to the right direction.

Stop testing and updates for CentOS 7 / RedHat 7
by Martin Winter 09 Jan '25

09 Jan '25

Hi there, I'm planning to stop releasing any new CentOS 7 / RedHat 7 packages and stop the testing for it. - No more CI tests on CentOS 7 - No new packages for CentOS 7 / RedHat 7 (not even minor updates or security fixes) CentOS 7 is EoL for some time. So far, we still used it for build Redhat 7 / CentOS 7 packages, but there is now the time where repositories get removed or moved. As such, I think the work to maintain this in the CI Infrastructure and Release Build is too much and I'm considering abandoning it. This does NOT impact RedHat 8 or RedHat 9. Please reply if this causes any issues to you or have any other reasons why this should be reconsidered. Regards, Martin Winter
