Hi, I am looking into adding support for DHCP Relay to Honeycomb.
I found one dhcp yang model (ietf draft): https://tools.ietf.org/html/draft-liu-dhc-dhcp-yang-model-05#section-2.3 but it is not well suited (supports only ip4, configuration is per interface, not per vrf as in vpp case). >From quick look at the code I looks like (please correct me if I am wrong): 1) There can be one dhcp proxy per <rx_vrf_id, is_ip6> pair. 2) VPP will not relay DHCP messages if insert_circuit_id is not set to 1 (parameter of dhcp_proxy_config_2 msg). 3) DHCP request will not be forwarded if client interface is assigned different vrf than dhcp proxy (rx_vrf_id). 4) There is no binary api to list configured dhcp proxies (only show dhcp proxy CLI cmd). Regards, Marek
