in-path deployment Core online with Edge offline (<= 0.1.8)

[peter]

Hi,
It is actualan old question which was leave one wanos ( here was the core ) on inpath broke whole network.
reproduce
looking for
client --- wanos(edge) --- route --- wanos(core) --- server

1. build network
client --- route --- server
everthing works : client can http ftp cifs server

2. put wanos (core) into network
client --- route --- wanos(core) --- server
nothing works: client can not http ftp cifs server

3. put wanos (edge) into network
everything works again.

As my understanding, step 2 should be working with no optimization. My test environment is vmware workstaion 10 with dedicate wan0 and lan0 interfaces. 
Or, I am missing something over here. Otherwise, in reality, there is no way you can put core and edge device up at the same time.

Hi Peter,

Previously fail-over was for the core only, since it is normally the most critical point in the network. Edges would detect when the Core was up or down. (<= 0.1.8 )
Currently peer discovery/fail-over/ is enabled for either end. Cores and Edges can detect when a peer goes down. (>=1.2.1)

So while it is probably still a good idea to enable the Cores last as per the step-by-step guides, it is not absolutely required anymore.
