Subject: [PATCH ovn 2/3] controller: fix ip buffering with static routes
|
|
|
bbaaef |
|
|
|
bbaaef |
When the arp request is sent to a gw router and not to the final
|
|
|
bbaaef |
destination of the packet buffered_packets_map needs to be updated using
|
|
|
bbaaef |
next-hop ip address and not the destionation one.
|
|
|
bbaaef |
|
|
|
bbaaef |
Fixes: 2e5cdb4b1392 ("OVN: add buffering support for ip packets")
