There is another thread that had similar concern:http://www.mail-archive.com/nox-dev@noxrepo.org/msg02563.html For IP routing to work across subnets: - The IP router should reply to ARP from both subnets - Any pkt with dst MAC being that of the IP router should be fwded to real destination, only after dest MAC is replaced. - For finding the ultimate dest MAC, the IP router should perform ARP request for the ultimate dest IP None of the above is performed by the NOX routing module. If you do manage to develop the code for this, please feel free to mail appropriate modules/code to the list. 2011/12/6 王健 <wangjian2008_12...@126.com> > Hi Murphy: > I am confused about a question about OpenFlow dedicated switch for a > long time.The following is my testing network topology: > > PC1 and PC2 can ping each other successfully if they have the same net id, > and can't ping successfully if they don't. > Does OpenFlow dedicated switch only surpport layer 2 processing when run > the command : nox_core -v -i ptcp:6633 discovery topology authenticator > routing?
