Re: [vpp-dev] VPP router plugin

[Ni, Hongjun]

+ vpp-dev

Hi Bhanu,

Please see attached patch for router plugin in VPP 17.01 branch.

We used BIRD when using VPP 17.01 after only using attached router_1701.patch.

The patch https://gerrit.fd.io/r/#/c/5881/ is only used for VPP 17.04 branch.

Below are building commands:
cd /root/vpp
ln -sf /root/vpp/vppsb/netlink
ln -sf /root/vpp/vppsb/router
ln -sf /root/vpp/vppsb/netlink/netlink.mk build-data/packages/
ln -sf /root/vpp/vppsb/router/router.mk build-data/packages/

cd /root/vpp/build-root
make V=0 PLATFORM=vpp TAG=vpp netlink-install router-install

ln -sf /root/vpp/build-root/install-vpp-native/router/lib64/router.so.0.0.0 
/usr/lib/vpp_plugins/router.so

Hi Hongjun,

  We are trying to build dynamic routing daemon with VPP 1701/1704 branch. 
As part of that we are going through building the netlink and router plugins.
  I see your post "[vpp-dev] Building router 
plugin" and also 
patch (https://gerrit.fd.io/r/#/c/5881/). You also said that you have another 
patch for VPP 1701 branch. Could you please send it?
 Were you able to run Quagga/BIRD using VPP 1701 after applying the above 
two patches?

 Please help me with the required patches and steps to build netlink and 
router plugins with VPP 1701 branch. Also I would like to compile these plugins 
with external DPDK source. Could you please help me on this?


Regards,
Bhanu,

[vpp-dev] thread handling tx

[Yuliang Li]

Hi,

How can I see the thread that handles the tx of each interface? I can use
the "show int rx" to see which thread is responsible for rx, but I want to
also see the tx.

Thanks,

Ip4-inacl != ip4-classify. If you want packets to visit ip4-classify, you need 
to install a classify adjacency in the FIB. See .../ip/lookup.c / “ip route 
1.2.3.4/8 via classify ” debug CLI command.

I understand that not having things work the way you expect them to is 
frustrating. I would love to be able to drop everything and answer questions 
immediately, but that’s not practicable.

Thanks Shwetha

Have you enabled the classifier on GigabitEthernet1b where you are receiving 
the packets?

set int input acl intfc GigabitEthernet1b… ip4-table 0

Hi,
Possibly a repeat question on classifier. But could not get much help from 
other threads on this regards.
I am trying to send UDP traffic from 10.10.122.117 to 10.10.121.179 and expect 
those to hit to my plugin "my4-dl-input"
Don't even see the ip4-classifier in the packet tracer.

Below is what I set and see the classifier table and session using CLI.

It means that in the message stream in response to the dump call you got an 
unexpected message type. That could be caused by an error in api definition or 
something else. 

Could you give me steps to reproduce, which api calls etc. 

Cheers
