Hi All, I would like to see multipoint LDP FEC elements like

ldp.msg.tlv.ldp_p2mp.addr_len   Address Length  Unsigned integer, 1 byte    1.12.0 to 2.4.2
ldp.msg.tlv.ldp_p2mp.ipv4_rtnodeaddr    Root Node Address   IPv4 address    1.12.0 to 2.4.2
ldp.msg.tlv.ldp_p2mp.oplength   Opaque Length   Unsigned integer, 2 bytes   1.12.0 to 2.4.2
ldp.msg.tlv.ldp_p2mp.opvalue    Opaque Value    Sequence of bytes   1.12.0 to 2.4.2
ldp.msg.tlv.ldp_p2mp.type   P2MP Type   Unsigned integer, 1 byte    1.12.0 to 2.4.2

I see that they are supported but when I open a capture with these packets wireshark cannot decode them

I used 2.4.2 on Windows and 2.2.6 on linux, same results, any ideas?

Thanks.
