The "physical system" works well... Thank you! David
That's good to know, thanks for the feedback! -Lori

It's not identical, but it's quite similar. What is tap0 in README-lisp becomes eth0 (EID space) and eth0 becomes eth1 (RLOC space). However, the RLOC interface is not strictly required to be in the bridge. I haven't tested LISP with physical hosts like this, but it should work. -Lori I'm sorry to bothrer you David Il giorno 02/giu/2014, alle ore 14:19, Lori Jakab <[email protected] <mailto:[email protected]>> ha scritto: On 5/30/14, 8:07 PM, David Lo Bascio wrote: I should create a LISP-type Ingress/Egress Tunnel Router using Open vSwitch... that's the configuration: - A PC with Open vSwitch installed has 2 physical interfaces (eth0, eth1) and it musts behave as a LISP xTR; i'll call it OVS. So far, so good... - Host1 is in EID space, so it has an EID IP address on its eth0 interface and it is connected to OVS'br0, which has an EID IP address belonging to the same subnet of Host1. OK... - OVS'br1 is in RLOC space, so it has an RLOC IP address, in the same subnet of Host2. You don't need the extra bridge br1 in order to have a LISP xTR in node 'OVS'. You only need eth0 and a lisp0 interface configured as described in README-lisp inside br0, and br0 configured with an EID address. - Host2 is in RLOC space, so it has an RLOC IP address on its eth0 interface and it's connected to OVS'br1. In that case, Host 2 will see a LISP encapsulated packet, and will not know what to do with it. If you want to communicate from Host1 with another host, that other host needs to be in EID space. So you need a symmetrical setup (a second xTR) to decapsulated packets and terminate the tunnel. In OVS, eth0 is attached to br0 and eth1 to br1; i have created on br1 the lisp OF port and tunnel to Host2'eth0. See above, br1 is not necassary, and the lisp tunnel interface should be also part of br0. How defining flows on br0 and br1 to exchange lisp packets between Host1 and Host2? Or better, how connecting br0 and br1 in OVS, so that traffic coming from Host1 and passing through OVS'eth0/br0 can arrive to br1/lisp interface? You need two OVS nodes to exchange packets between Host1 and Host2. HTH, -Lori Thank you very much!
