Introduction
Insert the following paragraph and list items at the end of 1.3:
This standard also specifies further protocol extensions, procedures, and managed objects to IS-IS for providing capabilities beyond Shortest Path Bridging (SPB) for Bridged Networks. These extensions involve explicit path control, bandwidth reservation, and redundancy (protection, restoration) for data flows. Thus, this standard specifies bridging on explicit paths for unicast and multicast frames, specifying protocols to determine multiple active topologies. To this end it
ca) Describes the use of explicit trees, e.g., to improve resiliency and decrease the probability of congestion.
cb) Requires that active topologies calculated by one or multiple entities external to the routing protocol are such that the characteristics of the MAC Service are provided.
cc) Supports management selection of explicit trees for support of any given VLAN within an SPT Region.
cd) Specifies Intermediate System to Intermediate System Path Control and Reservation (ISIS-PCR): the use of and extensions to the Intermediate System to Intermediate System (IS-IS) protocol to establish explicit trees.
ce) Specifies the use of ISIS-PCR for recording bandwidth assignments.
cf) Specifies redundancy for ISIS-SPB and ISIS-PCR.
