Hi All, I am having a problem for ovn and need help, thanks.
I created two logical routes and connected the two LogicalRoutes
through a external LogicalSwitch (connected to the external network) .
And then LogicalRoute-1 connected to the VM through the internal
LogicalSwitch .
my topology:
10.157.142.3 172.16.1.254
+--------------------+
+---------+--------+ +---------+--------+
+----------------+ Logical Router 1 +------------------|
Logical Switch +-------------------+ VM 172.16.1.7 |
| +--------------------+
+------------------+ +------------------+
+---------+--------+
| Logical Switch |
+------------------+
| +--------------------+
+----------------+ Logical Router 2 |
+--------------------+
10.157.142.1
I tested the master and Branch2.7, it Can not be transferred from VM
(172.16.1.7) to LogicaRouter-2 's port (10.157.142.
Sorry, The destination address is 10.157.142.1, And The SNAT/unSNAT
address is 10.157.142.3.
) via ping.
My logical router is a distributed gateway, and the two logical router
ports that connect external LogicalSwitch are on the same chassis.
If the two logical router ports are not on the same chassis ping is
also OK, And ping from VM (172.16.1.7) to external network is also OK.
I looked at the openflow tables on gateway chassis, I suspected
unsnat handling error in Router1 input for icmp replay.
I think it is necessary to replace the destination address
10.157.142.3 with 172.16.1.7 in Table 19 and route 172.16.1.7 in Table
21, but now the route match is 10.157.142.0/24.
