[vpp-dev] IPv4 Option field

2017-06-29 Thread Soheil Abbasloo
Hi all, This is Soheil. We are working on a project involving the IPv4 In-Band OAM. I have tried to use VPP in a simple scenario (like the simple switching/routing tutorial in fd.io) to pass IPv4-Options (in out case TIMESTAMP option) between two containers. However, packets having IP-Option fiel

Ole, We are in the design phase and investigating different platforms to see which one might be used in our scenario. Here, I don't wannna discuss the characteristics of a software router solution we all already know that! But simply one of the key properties of a software solution like VPP should

Ole, > Now, all this said... I understand the temptation of the solution and while I think it is likely a bad idea, and likely undeployable, nothing would stop you from trying it out in VPP if you like. There is some code that assumes the TCP header follows a 20 byte IP header, but that could easi
