What it actually says is: sname 64 Optional server host name, null terminated string. So yes, you're semantically correct. I forgot in the original DHCP this was a static field and not a TLV. In DHCPv6 however it doesn't exist. Chris. _______________________________________________ vpp-dev mailing list vpp-dev@lists.fd.io https://lists.fd.io/mailman/listinfo/vpp-dev
