[ovs-discuss] SFC with NSH

[Hoàng Công Phước]

Hi folks,

I am using Open vSwitch to create service function chain with NSH (network
service header) enabled. However, I have a bug when I add new flow rule to
bridge. Here are my command to add flow rule manually:
$ sudo ovs-ofctl add-flow br-int "table=0,
tcp,in_port=11,nw_src=10.10.0.8,nw_dst=10.10.0.0/24,tp_dst=1024
actions=encap(nsh(md_type=1)),set_field:0x33->nsh_spi,set_field:255->nsh_si,encap(ethernet),group:1"

As the error log, it shown: bad action at offset 0
(OFPBAC_BAD_VENDOR_TYPE). More detail in this link:
http://paste.openstack.org/show/739456.

My Open vSwitch environment: ovs-vswitchd (Open vSwitch) 2.9.0. As I known,
NSH feature was already merged into master branch of Open vSwitch in
version 2.9.0. I want to known what I should do to fix that issue or . I
hope someone can help me about it. Thank in advance.

Best regards,
Phuoc Hoang Cong
