at the moment, the default route is correct now, the higher priority is
contributing to forwarding. but others with red color also use the wrong
default route.

Hello vpps
1. first we add a default route using api like this:
ip route add 0.0.0.0/0 via 10.121.20.1 weight 1 preference 20
2. than add some other routes which will stacked on default route above
3. add another defalut route using api with same weight value but higher

ip route add 0.0.0.0/0 via 1
[vpp-dev] questions about fib
Hello vpps 1. first we add a default route using api like this: ip route add 0.0.0.0/0 via 10.121.20.1 weight 1 preference 20 2. than add some other routes which will stacked on default route above 3. add another defalut route using api with same weight value but higher priority (lower preference value) like this: ip route add 0.0.0.0/0 via 10.120.0.253 weight 1 preference 0 my question is: when the third step completed, does routes added by step 2 will stacked on the new default routes added by step 3? actually the default route added by step 3 is correct. I think step 3 route is higher priority than step 1, when it's added, it will back forward to all its children, am i right ? or did i miss something ?

Re: [vpp-dev] how BIRD routes integrate into vpp
Thanks very much, now my vpp and bird could work together. we hope some routes that BGP received not be added to kernel route table, so that the default kernel table won't be impacted, meanwhile we hope these routes to be added to vpp. we have tried several methods, none could acheive this goal, do you have any suggestions? haiyan...@ilinkall.cn From: Pim van Pelt Date: 2022-04-24 16:56 To: haiyan...@ilinkall.cn CC: vpp-dev Subject: Re: [vpp-dev] how BIRD routes integrate into vpp Hoi, 20.01 is somewhat old. Synchronizing routes from bird or frr is possible, although you'll want to run Linux Control Plane plugin (pertinent gerrit: https://gerrit.fd.io/r/c/vpp/+/31122) which was merged in time for the last release 21.10. I wrote a set of articles on the Linux CP plugin here: https://ipng.ch/s/articles/ (see the 7 posts marked "VPP Linux CP" for lots of background). You could try to compile the plugin on 20.01 but I'm certain you'll have to make some changes on your own, as the codebase has evolved quite a bit since your 20.01 release from 2020. You can also take a look at a screencast I made that shows the plugin (that reads exactly from Bird as you wish): https://asciinema.org/a/432943 groet, Pim On Sun, Apr 24, 2022 at 9:32 AM haiyan...@ilinkall.cn wrote: Dear All: I'm going to use BIRD(BGP) working together with VPP, but how can I synchronize BIRD routes to VPP, any suggestions or reference?

Re: [vpp-dev] about in/out arguments in "set interface nat44 .."command
Hi Filip, There are two kinds of traffic in my test. one is managing traffic, which will comes into vpp only from a tap interfaces, for example tap's ip address is 10.10.1.1/24. we need these traffic to do snat and out from G0 one is business traffic, which are gererated interlanfrom vpp, these traffic will not do snat and out from G0 Both the two kinds of traffic share the same outside interface G0 which could access the internet. I have tried: 1. seperate managing traffic into different vrf, ... 2. add static mapping for local 10.10.1.x/24 external , ... but both did not work. can vpp achieve this goal? any suggestions will be appreciated. haiyan...@ilinkall.cn From: Filip Varga -X (fivarga - PANTHEON TECH SRO at Cisco) Date: 2022-03-12 02:27 To: haiyan...@ilinkall.cn; vpp-dev Subject: RE: [vpp-dev] about in/out arguments in "set interface nat44 .."command Hi Haiyan, Can you please be more specific. For example what other traffic except from interface A and B will be passing (are there other interfaces involved) ? Using nat44-ed forwarding is a bit tricky. It let’s pass traffic without translation if a preexisting session isn’t found so this would mean only static mapping get’s translated. Forwarding feature is used for specific purposes when in mixed environments you have A configured as inside and also outside and B configured as inside and outside also.

VRF2: Configure one or all interface (that you want to be able to communicate with public IP addresses) as inside interface[s] for nat44-ed plugin. 3) Configure nat44-ed address range for VRF2. tenant-vrf parameter is used to tell nat for which source VRF the address should be used for translation. So in this scenario we need it to be VRF2.

[vpp-dev] how to understand vpp "show runtime" command?
Hi, vpp experts, I test vpp multithread case, each thread with one cpu core, with linux "top" command, I can see used cpu reached 100%. really confused if cpu still can process more work. someone said that vpp command "show runtime" could do this, but I could not fully understand these arguments, is there some documents can be referenced , or someone kindly explain it for me, any suggestion will be appreciated. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
