Yocto Recipe for FRR
by Amol Lad 10 Aug '21

10 Aug '21

Hi, Please advise if there is any Yocto recipe for FRRouting? If not, how to go about creating one for FRR? Yocto Recipe for FRR will hugely simplify integrating FRR in Yocto based embedded linux distributions. So please advise if there are any plans to develop this recipe?

v6 Route Replace semantics
by Donald Sharp 08 Apr '20

08 Apr '20

All - We recently introduced, into master, a new cli switch for zebra on linux `--v6-rr-semantics`. This was allow zebra to take advantage of the linux kernel getting v6 route replace semantics that is coming soon in the 4.18 linux kernel. So if you are on the bleeding edge of linux kernels and FRR you can start to take advantage of this new feature. What are Route Replace semantics you ask? Suppose we have a v6 route with 2 nexthops: S>* 4:6:7::/64 [1/0] via 1:2:3::4, enp0s3, 00:00:02 via 1:2:8::8, enp0s8, 00:00:02 Now suppose we remove a nexthop: robot# conf t robot(config)# no ipv6 route 5:7:9::/78 1:2:8::9 robot(config)# end robot# show ipv6 route [snip] S>* 5:7:9::/78 [1/0] via 1:2:3::4, enp0s3, 00:01:04 Let's look at the netlink notifications for this event: [ROUTE]5:7:9::/78 proto static metric 20 <----------- From creation of the 2x ecmp for 5:7:9::/78 nexthop via 1:2:3::4 dev enp0s3 weight 1 nexthop via 1:2:8::9 dev enp0s8 weight 1 [ROUTE]Deleted 5:7:9::/78 proto static metric 20 <---- We delete the route nexthop via 1:2:3::4 dev enp0s3 weight 1 nexthop via 1:2:8::9 dev enp0s8 weight 1 [ROUTE]5:7:9::/78 via 1:2:3::4 dev enp0s3 proto static metric 20 pref medium <----- We add it back in. In order to get the routes right in the kernel we had to delete the route first and then add it back in. Exposing a small window of packets being dropped while the route is fixed in the fib. Route Replace semantics tells the linux kernel to just replace the nexthops for the route. New packets coming in would immediately start using the new ecmp nexthop group path: [ROUTE]5:7:9::/78 proto static metric 20 nexthop via 1:2:3::4 dev enp0s3 weight 1 nexthop via 1:2:8::9 dev enp0s8 weight 1 [ROUTE]5:7:9::/78 via 1:2:3::4 dev enp0s3 proto static metric 20 pref medium thanks! donald

CentOS7 and vxlan setup
by Chris Smith 23 Sep '19

23 Sep '19

Hi, I'm using frr 4 and I'm struggling to set up vxlans similar to the example here: http://docs.frrouting.org/en/latest/pim.html?highlight=vxlan#pim-evpn-confi… Using that config gives me a bunch of 'unknown command' errors because they are debian style interfaces. Switching what I can to the redhat style interface doesn't help, I still get stuck with 'vxlan-id' and 'vxlan-local-tunnelip' being unknown commands (let alone trying to get the bridge device working). My google fu is failing and the closest I came was https://lxadm.com/Unicast_VXLAN:_overlay_network_for_multiple_servers_with_… Though I'm not sure how I fit that together with frr. Does anyone have a complete example I can use with centos7? Thanks, -- Chris Smith System Administrator csmith(a)squiz.com.au Level 1, 435a Kent St, Sydney NSW 2000 P +61 2 9045 2800

Hello list, i'm trying to get an linux kernel routing table entry like this one: # ip r get 52.218.237.186 52.218.237.186 via 192.0.2.2 dev br99 src 37.228.152.3 but frr always creates entries like this one: # ip r get 52.218.237.186 52.218.237.186 via 192.0.2.2 dev br99 src 192.0.2.3 37.228.152.3 is an ip of an dummy0 interface and 192.0.2.3 is the ip of br99. frr.conf: router bgp XXXXX bgp router-id 37.228.152.3 neighbor internal-bgp peer-group neighbor internal-bgp remote-as XXXXX neighbor internal-bgp capability dynamic neighbor 37.228.152.2 peer-group internal-bgp neighbor 37.228.152.2 description R2 neighbor 37.228.152.2 update-source dummy0 ! address-family ipv4 unicast neighbor 37.228.152.2 next-hop-self exit-address-family !

Question about PIM
by kevin-chiang 03 Sep '19

03 Sep '19

Dear developers, We have some questions about pimd: According to my test, seems FRR can't handle IGMPv3 report with exclude mode (system still forwards the specified multicast data packet which is received from exclude source IP) ==> Does FRR support IGMPv3 report with exclude mode?? ==> Or any bug fix plan in the future? If we enable IGMP only, then multicast data packet can't forward succeeded, seems we must enable PIM also. ==> Dose FRR have any plan to support only IGMP enable case?? Please guide us Thanks a lot BRs Kevin Loop Telecommunication International, Inc. www.looptelecom.com 8GESW is designed to transport Ethernet services over SDH/SONET networks (EoS). It provides eight GbE ports and a range of standard L2 switch functions, including VLAN, Q-in-Q, MAC learning, MSTP/RSTP, CoS and QoS, and etc. Ethernet bridging services include EPL, EVPL, and EPLAN. Max. bandwidth for SDH/SONET transportation is either STM-4/OC-12 or STM-16/OC-48. Dual 8GESW cards can be mounted simultaneously to achieve card-level protection. Protection switch happens within 50 ms without any traffic interruption. Traffic at the SDH/SONET side is further protected by SNCP/UPSR ring and MSP (1+1).

Hi! If i think correctly FRR doesnt support BGP de-aggregation of routes (in Cisco term bgp inject-map) https://www.noction.com/blog/bgp-conditional-route-injection There is a plan to support this or similar feature? thx csszep
