According to the labbing I've done tdp also announces implicit-null label for PHP: R1#sh mpls interfaces. The Border Gateway Protocol (BGP) is the routing protocol of the Internet. Five things you should know about Cisco IOS BGP configuration. Unspecified vulnerability in Cisco IOS 12.0 through 12.4, IOS XE 2.1.x through 2.3.x before 2.3.2, and IOS XR 3.2.x through 3.4.3, when Multiprotocol Label Switching (MPLS) and Label Distribution Protocol (LDP) are enabled, allows remote attackers to 'Affected Products Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software devices are vulnerable if they are configured to listen for either targeted LDP hello messages or link LDP hello messages. Interface IP Tunnel Operational Serial1/0.10 Yes (tdp) No Yes. I picked up the first two, and they came out to around 100 bucks. MPLS Configuration on Cisco IOS Software is a complete and detailed resource to the configuration of Multiprotocol Label Switching (MPLS) networks and associated features. Devices that are running Cisco IOS XR software are not vulnerable. I will probably pick up MPLS Fundamentals, Definitive MPLS design, and MPLS Configuration on Cisco IOS Software today. No other Cisco products are currently known to be affected by these vulnerabilities. Devices that are not configured for MPLS are not vulnerable. 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.
