| SNAC Router Flag in ICMPv6 Router Advertisement Messages | ||||||||||||||
|
This document defines a new flag, the SNAC Router flag, in the Router Advertisement message that can be used to distinguish configuration information sent by SNAC routers from information sent by infrastructure routers. This flag is used only by SNAC routers and is ignored by all other devices. | |||||||||||||
| BIER Penultimate Hop Popping | ||||||||||||||
|
This document specifies a mechanism for Penultimate Hop Popping (PHP) in the Bit Index Explicit Replication (BIER) architecture. PHP enables the removal of the BIER header by the penultimate router, thereby reducing the processing burden on the final router in the delivery path. This extension to BIER enhances operational efficiency by optimizing packet forwarding in scenarios where the final hop's capabilities or requirements necessitate such handling. The document details the necessary extensions to the BIER encapsulation and forwarding processes to support PHP, providing guidance for implementation and deployment within BIER-enabled networks. | |||||||||||||
