- Summary
- Q: A BGP adjacency establishes between PEs, but private network packets cannot forward normally. What is the problem?
- Q: In the BGP/MPLS VPN networking of the inter-AS Option B, proper adjacencies establish between ASBRs, but private network packets cannot forward. What are the causes?

- About this chapter
- 4.1 MPLS Layer 2 VPN overview
- 4.3 Troubleshooting cases
- 4.3.1 VC type is not supported when setting up a PW on an ATM subinterface
- 4.3.2 A static PW cannot be switched with other PWs
- 4.3.3 Switch-L2VC is down after PW switching configuration
- 4.3.4 PW attributes cannot be changed by using the reset pw command
- 4.3.5 VC is up but the PPP session cannot establish
- 4.3.6 VC under the interface is missing after the link protocol changes
- 4.3.7 Both the session and the AC are up, but the VC cannot be up
- 4.3.8 Ethernet interconnects with ATM, the VC is up, but the ping between CEs fails
- 4.3.9 CEs cannot communicate by using the accessing mode of VLAN
- 4.3.10 CEs cannot access each other though the static VC is up
- 4.3.11 VC is down though AC is up
- 4.3.12 Large-sized packets are lost between CEs on two ends of Layer 2 VPN
- 4.3.13 Failure to establish the MPLS LDP session between PEs when RIP-1 is used in the Layer 2 VPN backbone
- Fault symptom

- Troubleshooting procedure
- Summary
- Q: How can I run Martini mode on the existent version?
- Q: In what cases do I configure local-ce and local-mac in different media interworking?
- Q: What special configuration should be done on an FR interface? What is the configuration guideline when CE acts as DCE and PE functions as DTE?
- Q: What is the function of the control word in Layer 2 VPN?
- Q: Can I specify multihop VCs with the same peer and different encapsulation types when I configure switch-Layer 2 VC on SPE?
- Q: Can I set the PW ID to 0 or ignore the configuration?
- Q: How can I configure Layer 2 VPN load balancing?
- Q: What does the multihop mean in Layer 2 VPN? In what cases is multihop used? How can I configure multihop?
- Q: Why can the same Layer 2 VC be configured with two types of encapsulation when MPLS switch-Layer 2 VC is configured on SPE?
- Q: What are the conditions for a PW being up?
- Q: What are the differences between tag or untagged configuration in the Ethernet interface view and tagged or raw configuration in the PWE3 view?
- Q: After CEs adopt the ATM to access PEs, all the CE interfaces and PE interfaces are up. Why can the CEs on two ends not ping through each other?
