Hi ALL,

In RFC5329, OSPFv3 TE Link TLV have below sub-TLVs
18 - Neighbor ID (8 octets) ： Neighbor Interface ID ， Neighbor Router ID
19 - Local Interface IPv6 Address
20 - Remote Interface IPv6 Address

question1：
4.4. Remote Interface IPv6 Address Sub-TLV
if link-LSA not have a prefix length of 128 and the LA-bit
how to get remote Interface ipv6 address to fill the tlv value.

question2：
if router only advertise :
18 - Neighbor ID (8 octets) ： Neighbor Interface ID ， Neighbor Router ID
19 - Local Interface IPv6 Address
how to match router's TE Link TLV with peer router's TE Link TLV

question3：
4. Link TLV --- " The Neighbor ID sub-TLV is mandatory for OSPFv3 Traffic Engineering support. "
it means Local Interface IPv6 Address Sub-TLV is not mandatory
if only advertise : 18 - Neighbor ID (8 octets)
how to match router's TE Link TLV with peer router's TE Link TLV

Thanks,
Jenny

In section 4 Link TLV：
