1. New Traffic Path UI
  • The new UI allows users to set directions of path discovery (A to B, B to A or bi-directional)
  • Users can set gateway for the return path now, which is important for path discovery related to NAT
  • Virtual IP address from HSRP/VRR/GLBP will be automatically selected as the gateway. Otherwise, router with the smallest IP address is selected

2. Show Details of Path Discovery Logic

New path logic displays hop-by-hop route table entries, along with drill-down menu options, so that users can better understand how a candidate path is selected. If there are ACL, VRF, PBR or NAT configured in the current hop, relevant data is displayed so that users can further decide if the path is impacted by these configurations.

3. Internet Boundary

If a traffic path flows to the Internet, or any 3rd party network (e.g. partnerís extranet), users can define a boundary cloud such as ďInternetĒ off a border routerís interface. When a path flows through a border routerís specific interface, the cloud will be added as the next hop.

I look forward to trying both of those last two features. The Internet boundary WILL be a big help and the L2 live discovery seems promising.
