A city clerk must separate underlay label-switched path problems from CE routing problems. Which tools are purpose-built for LSP validation?
Select an answer to reveal the explanation.
Short Explanation
Regular ping to a CE LAN host won’t tell you if labels are healthy. MPLS ping and MPLS traceroute speak LSP language and show where the label path breaks. Use the right OAM wrench.
Full Explanation
MPLS ping and MPLS traceroute are OAM tools that validate LSP forwarding and localize underlay label problems independently of CE IP routing success. A plain ICMP ping to a CE LAN address can succeed or fail for reasons unrelated to the core LSP. STP traps and DHCP snooping address different layers and domains.
