| The above nexthop type will need ATTR_TUNNEL_ID as well as ATTR_IP as mandatory parameters on creation. |

ATTR_IP will be mandatory for p2mp mode only. For p2p mode, the tunnel destination IP will come the tunnel object.

Please double check the naming of isogrp_mbr_oid. I think the first two can be renamed to isogrp_mbr_oid_22 and isogrp_mbr_oid_32 respectively.
nit: swap lines 3 and 4, so 3 lines for LAG-2 are together.

Host may be reachable via multiple VTEPs in the EVPN topology. In this case load balancing need to happen across VTEPs.
This is achieved using a new bridge port type SAI_BRIDGE_PORT_TYPE_BRIDGE_PORT_NEXT_HOP_GROUP that is going to use SAI_BRIDGE_PORT_ATTR_BRIDGE_PORT_NEXT_HOP_GROUP_ID for nexthop selection. Nexthop wll be the one of the available VTEP tunnels.
There can be an associated protection NHG configured SAI_BRIDGE_PORT_ATTR_BRIDGE_PORT_PROTECTION_NEXT_HOP_GROUP_ID, as a backup path in case the bridge port goes down.
