Hi,
I am working on simple topology as follows:
C
/ | \
Veth ports-----S1 -- S2 -- S3 ---- H1
\ /
S4
I am sending raw packets cooked with GRE headers on Veth ports. I want to
create rules based on GRE key value like this:
match2 = parser.OFPMatch(in_port=2, eth_dst=dst, eth_type=0x0800,
ip_proto=47, *grekey=XXXXX*)
S1 will decide where to send the packet based on gre key information.
Port on S1 connected to veth ports can receive non-gre packets(TCP etc) as
well and there is are no tunnels configured.
Can you help with how to define rules such as above, I am using ryu as
controller.
Regards
