Help understanding Tunnel Term Tables in VxLan, NvGRE and TunnelDecap

[mholankar]

Why is the DST_IP not added for P2P tunnel?

sonic-swss/orchagent/tunneldecaporch.cpp

Line 506 in e6f134f

// Set src ip for P2P only

Why is the dst_ip set for the SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_SRC_IP attribute?

sonic-swss/orchagent/vxlanorch.cpp

Line 417 in e6f134f

attr.id = SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_SRC_IP;

and why is src_ip set for the SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_DST_IP attribute?

sonic-swss/orchagent/vxlanorch.cpp

Line 426 in e6f134f

attr.id = SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_DST_IP;

again why is src_ip set here for the SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_DST_IP attribute?

sonic-swss/orchagent/nvgreorch.cpp

Line 232 in e6f134f

attr.id = SAI_TUNNEL_TERM_TABLE_ENTRY_ATTR_DST_IP;
