Path Technologies for Different Vendors

NetBrain dynamic path feature visualizes the forwarding of the packet and emulates the real packet forwarding process by looking up route tables in your live network and provides end-to-end visibility across any network path. Besides looking up route tables to find the next hop, It can also look into PBR, NAT, ACL, firewall policy and other traffic control technologies to ensure the correctness of a path.

This document introduces the vendors and device types that the system supports to parse in terms of the following special path technologies when calculating a path:

• Policy
• ACL
• PBR
• NAT
• SNAT
• MPLS VPN
• IPsec VPN
• GRE VPN
• MPLS TE
• Fabricpath
• OTV
• VPLS
• VXLAN

Tips:  See the Multiple-vendor Support List for details about a device type's basic traffic path support. If a device type is in the Tier-2 level, it means that this device type supports the basic L2 or L3 traffic path in the system.  For devices that the system does not recognize these special technologies as described above, you can use the traceroute function to obtain the traceroute hops and draw the path on a map with the traceroute hops.
