MPLS Configuration on Cisco IOS Software Lancy Lobo, Umesh Lakshman
XS before 3.7.2S, when MPLS-TE is enabled, allows remote attackers to cause a denial of service (incorrect memory access and device reload) via a traffic engineering PATH message in an RSVP packet, aka Bug ID CSCtg39957. If you want to know what this MPLS thing is all about. Alright, let´s perform mutual redistribution for Customer B on R1 and R4: First we redistribute EIGRP into BGP on R1 and R4. MPLS QoS is outside the scope of this document. This document reviews how to configure Cisco IOS® Software congestion management and congestion avoidance features on the Cisco 12000 Series Internet Router. Cisco IOS Software and Cisco IOS XE Software contain a vulnerability in the RSVP feature when used on a device configured with VPN routing and forwarding (VRF) instances. Name: 20130327 Cisco IOS Software RSVP Denial of Service Vulnerability. Basic MPLS configuration on IOS XR 4. This is not at all true for MQC. Cisco.Press.MPLS.Configuration.on.Cisco.IOS.Software.Oct.2005.eBook-DDU< Day Day Up > MPLS Configuration on Cisco IOS Software By Lancy Lobo, - CCIE No. After you read this document, you must be able to: Understand why it is important .. Source: MPLS configuration on Cisco IOS software, Author: Lancy Lobo. This vulnerability could allow an unauthenticated, remote attacker to cause an interface wedge, which can RSVP-Traffic Engineering (RSVP-TE) in Multiprotocol Label Switching (MPLS) infrastructures * Multi-VRF infrastructures * VRF-Lite infrastructures. Hyperlink:http://tools.cisco.com/security/center/content/CiscoSecurityNotice/CVE-2013-1143. I recommend reading the chapter 'MPLS VPN Routing Model' from MPLS Configuration on Cisco IOS Software by Lancy Lobo CCIE No. Configure enhanced switching technologies (including Rapid Spanning Tree Protocol [RSTP], Multiple Spanning Tree [MST], and Per VLAN Spanning Tree [PVST]) on Cisco IOS Software switches; Describe how VLANs create logically Cisco routers; Describe carrier-grade NAT (CGN) and Network Address Translation 64 (NAT64); Describe Multiprotocol Label Switching (MPLS) functions in the service provider IP NGN; Configure Label Distribution Protocol (LDP) on Cisco routers. The router treats the MPLS bits as though they are IP Type of Service (ToS) bits and puts the appropriate packets into the correct queues.
