RFC 5302 Domain - wide Prefix Distribution
نویسندگان
چکیده
This document describes extensions to the Intermediate System to Intermediate System (IS-IS) protocol to support optimal routing within a two-level domain. The IS-IS protocol is specified in ISO 10589, with extensions for supporting IPv4 (Internet Protocol) specified in RFC 1195. This document replaces RFC 2966. This document extends the semantics presented in RFC 1195 so that a routing domain running with both level 1 and level 2 Intermediate Systems (IS) (routers) can distribute IP prefixes between level 1 and level 2, and vice versa. This distribution requires certain restrictions to ensure that persistent forwarding loops do not form. The goal of this domain-wide prefix distribution is to increase the granularity of the routing information within the domain. Li, et al.

Domain-wide Prefix Distribution with Two-Level IS-IS
This document describes extensions to the Intermediate System to Intermediate System (IS-IS) protocol to support optimal routing within a two-level domain. The IS-IS protocol is specified in ISO 10589, with extensions for supporting IPv4 (Internet Protocol) specified in RFC 1195 [2]. This document extends the semantics presented in RFC 1195 so that a routing domain running with both level 1 and...
متن کاملRFC 5130 IS - IS Admin Tags February 2008 3 . 1 . 32 - bit
This document describes an extension to the IS-IS protocol to add operational capabilities that allow for ease of management and control over IP prefix distribution within an IS-IS domain. This document enhances the IS-IS protocol by extending the information that an Intermediate System (IS) router can place in Link State Protocol (LSP) Data Units for policy use. This extension will provide ope...
متن کاملUnicast-Prefix-Based IPv4 Multicast Addresses
This specification defines an extension to the multicast addressing architecture of the IP Version 6 protocol. The extension presented in this document allows for unicast-prefix-based allocation of multicast addresses. By delegating multicast addresses at the same time as unicast prefixes, network operators will be able to identify their multicast addresses without needing to run an inter-domai...
متن کاملRFC 6811 BGP Prefix Origin Validation
To help reduce well-known threats against BGP including prefix misannouncing and monkey-in-the-middle attacks, one of the security requirements is the ability to validate the origination Autonomous System (AS) of BGP routes. More specifically, one needs to validate that the AS number claiming to originate an address prefix (as derived from the AS_PATH attribute of the BGP route) is in fact auth...
متن کاملRfc 3769
With the deployment of IPv6 [1], several Internet Service Providers are ready to offer IPv6 access to the public. In conjunction with widely deployed "always on" media such as ADSL and the expectation that customers will be assigned a /48 IPv6 unicast address prefix (see RFC 3513 [3] and section 3 of RFC 3177 [2]), an efficient mechanism for delegating address prefixes to the customer’s sites i...
