BGP Tunnel Encapsulation Attribute Sub-TLVs
- Reference
- [RFC9012]
- Note
-
If the Sub-TLV Type is in the range from 0 to 127 (inclusive), the Sub-TLV Length field contains one octet. If the Sub-TLV Type is in the range from 128 to 255 (inclusive), the Sub-TLV Length field contains two octets. - Available Formats
