Hi, Peter,

I have one comment.

As I explained our draft, draft-fujita-mpls-crldp-crankback-00.txt, in the 
last IETF, there are several possibilities of indicating of links or nodes. 
If you use unnumbered point-to-point links between routers, you cannot 
specify IPv4 address of interfaces for IPV4 specificed link feedback TLV 
and IPV6 specified link feedback TLV. In that case, you have to use a 
routing protocol (OSPF etc) dependent TLV to indicate links or nodes.

Our draft specifies protocol independent TLV (using ER-HOPS information) 
and routing protocol dependent TLV (OSPF, ISIS-specific information). I 
guess that our draft could be an one of possible solution to indicate such 
links or nodes.

What do you think ?

Best regards,
