This is Shahram, I have a problem with GRE in mininet topology, and I really appreciate if you help me:
I have two Mininet topologies in two separate VMs. then I establish aGRE tunnel between 2 OVS switch (each switch is in one topology).
h1 --- s1 (in first vm 192.168.37.132)
h2 --- s2 (in second vm 192.168.37.131)
sudo ovs-vsctl add-port s1 s1-gre1 -- set interface s1-gre1 type=gre options:remote_ip=192.168.37.
sudo ovs-vsctl add-port s2 s2-gre1 -- set interface s2-gre1 type=gre options:remote_ip=192.168.37.
my problem: sometimes I have ping between h1 nd h2 (GRE OK) and sometimes no (Network unreachable). for example when I stop my mininet and run again, gre does not work
Would you please help me?
