Re: [vpp-dev] VPP MPLS VPN Configuration #vpp #mpls #vpn
Dear Neale, Thank you very much for your response. The way I asked my question might have been a bit confusing. Although I have read the wiki, I could not actually get the topology. By topology I mean what configurations may be applied on what device. Shortly, I need to know how to configure each and every one of my VPP devices according to the topology I have demonstrated. Thank you very much again -- Anthony -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] VPP MPLS VPN Configuration #vpp #mpls #vpn
Hello I am trying to implement the following network topology: I have trouble finding out a step by step configuration for my VPP devices to communicate over MPLS VPN. I have read the Wiki: https://wiki.fd.io/view/VPP/MPLS_FIB but still did not get what to do. I was wondering if someone could guide me precisely through how to config VPP appropriately according to above-mentioned network topology.

Re: [vpp-dev] Bond interface won't respond ping #vnet #vpp
Dear Steven Thank you very much. As you said Bond interfaces should have been bundled in order to act as L3. I have now ping and everything. Thanks again.

Re: [vpp-dev] Bond interface won't respond ping #vnet #vpp
Dear Steven Thank you very much for your quick and nice response. I suppose the beginning of my question might misguide you. Let me clear my test scenario: I have a Virtual Machine (VM1) which runs VPP and has an interface called GigabitEthernet0/8/0. I have another Virtual Machine (VM2) that it's interface (eth1) is in the same Kernel bridge as GigabitEthernet0/8/0 (and does not run VPP). So that I am able to ping GigabitEthernet0/8/0 easily (from VM2). After creating a Bond interface (in VM1) with LACP mode (and also setting the state up and giving it IP address) and binding GigabitEthernet0/8/0 to the Bond interface I have neither ping of GigabitEthernet0/8/0 nor Bond interface (from VM2). I traced packets and It seems Bond interface is able to receive ARP packets (and learn it), however is not able to respond back to it. So I went ahead and set arps (for VM2) so that it started to send ICMP packets and again Bond interface (in VM1) was able to receive it but could not respond to it. So my question really is: 1) Why don't Bond interface is not able to respond to either ARP or ICMP packets? 2) Is my config incomplete? (or maybe wrong) 3) Is it logical to ping a Bond Interface?

[vpp-dev] Bond interface won't respond ping #vnet #vpp
Dear all I was working on some LACP testing in VPP 19.01. I configured VPP like this: create bond mode lacp set interface state BondEthernet0 up bond add BondEthernet0 GigabitEthernet0/x/0 The 'GigabitEthernet0/x/0' has some IP address like '10.10.10.80/24' and before adding it as a slave to Bond interface, pinging the interface from another Virtual Machine with IP address '10.10.10.81/24' was all OK (Both interfaces are in the same switch). After binding GigabitEthernet to Bond, slave interface stopped responding . The trace looks like this: 00:02:07:006939: dpdk-input GigabitEthernet0/8/0 rx queue 0 buffer 0x494a: current data 0, length 98, free-list 0, clone-count 0, totlen-nifb 0, trace 0x0 ext-hdr-valid l4-cksum-computed l4-cksum-correct l2-hdr-offset 0 PKT MBUF: port 0, nb_segs 1, pkt_len 98 buf_len 2176, data_len 98, ol_flags 0x0, data_off 128, phys_addr 0x22b25300 packet_type 0x0 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0 rss 0x0 fdir.hi 0x0 fdir.lo 0x0 IP4: 52:54:00:16:b8:43 -> 52:54:00:d8:95:e0 ICMP: 10.10.10.81 -> 10.10.10.80 tos 0x00, ttl 64, length 84, checksum 0x168f fragment id 0xfb65, flags DONT_FRAGMENT ICMP echo_request checksum 0xb04d 00:02:07:010073: bond-input src 52:54:00:16:b8:43, dst 52:54:00:d8:95:e0, GigabitEthernet0/8/0 -> BondEthernet0 00:02:07:010103: ethernet-input IP4: 52:54:00:16:b8:43 -> 52:54:00:d8:95:e0 00:02:07:010129: ip4-input ICMP: 10.10.10.81 -> 10.10.10.80 tos 0x00, ttl 64, length 84, checksum 0x168f fragment id 0xfb65, flags DONT_FRAGMENT ICMP echo_request checksum 0xb04d 00:02:07:010139: ip4-not-enabled ICMP: 10.10.10.81 -> 10.10.10.80 tos 0x00, ttl 64, length 84, checksum 0x168f fragment id 0xfb65, flags DONT_FRAGMENT ICMP echo_request checksum 0xb04d 00:02:07:010154: error-drop ethernet-input: no error I thought Bond interface needs an IP so I tried to give it an IP as '60.60.60.60/24' and so change Virtual Machine's IP as '60.60.60.81/24' and tried to ping Bond interface this time.

[vpp-dev] VPP 19.01 C API gets segmentation fault #binapi #vpp #vppcapi
Hi
Recently I tried to learn VPP's C API and I found a sample C program in
https://www.marosmars.com/blog/managing-vpp-c-edition blog.
I have compiled the program like this:
gcc myprog.c -o myprog -lvppinfra -lvlibmemoryclient -lsvm
and it has been compiled successfully.
The problem is that when I try to run the program I will get segmentation fault
like this:
program received signal SIGSEGV, Segmentation fault.
mspace_malloc (msp=0x0, bytes=bytes@entry=20) at
/root/vpp/src/vppinfra/dlmalloc.c:4338
warning: Source file is more recent than executable.
4338 if (!PREACTION(ms)) {
And the back trace looks pretty like this:

My Operating System is Ubuntu 18.04.01 and I have tested this on Ubuntu 16.04
as well with the same result.
I was wondering if anyone could help me with the problem.
Thanks in advance for your help,
Best regards
