I'm in favor of adding support for non-Ethernet GRE. The issues are similar to those for LISP, which can also carry L3 data. There's a series currently under review (see the "nsh" patches at http://patchwork.openvswitch.org/project/openvswitch/list/) that adds support for this. I'd like to use the same approach for all L3 protocols. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
