Troubleshooting challenges in MPLS-enabled enterprise networks.
MPLS (Multi-Protocol Label Switching) technology enables creation of logically segregated networking domains, which coexist within the same hardware and carriage infrastructure. Examples of MPLS enabled networks could be international airport where each airline and airport tenants have their own logical network segment with specific security and operational requirements.
While MPLS offers great flexibility and scalability for provisioning of new network communities known as VRF (Virtual Routing and Forwarding), its configuration on the other hand could be quite complex and challenging to maintain and support. Troubleshooting of issues in MPLS-enabled networking infrastructure is very challenging task.
Whenever user experience network issues, it is very important to quickly determine following relationship:
• User PC –> Access Port/Switch–> VLAN–> SVI (Switch Virtual Interface), which is default gateway for this VLAN –> Community or VRF
Depending on the problem, the issue could be not with physical network connection but with routing tables within particular Community or VRF. User may need to access certain IP Address but route to this destination is missing from routing table of particular VRF. So you will need visibility into ip routing activity across all your VRFs.
MPLS device configuration could be quite complex and subject to configuration mistakes.
Enigma NMS will provide you with everything required to resolve any issues in MPLS-enabled enterprise networks quickly and efficiently.
Enigma will show you following MPLS specific information and relationships:
• All network clients connection information
• All MPLS configured network devices
• All configured VRFs
• Relationships between VRF and device interfaces
• Routing tables for all VRFs along with deleted/changed IP routes
• Latest and real-time configuration activity across your entire network domain
• Site specific network performance issues, such as over-utilised links, links with errors or discards, links with duplex mismatch, devices with software issues or over-utilised CPU and Memory.
Having all this information readily available will result in significant simplification and reduction of troubleshooting process.
