Viewing BFD Session Properties
Bidirectional Forwarding Detection (BFD) is used to detect communication failures between two
elements, or endpoints, that are connected by a link, such as a virtual circuit, tunnel, or LSP. BFD
establishes sessions between the two endpoints over the link. If more than one link exists, BFD
establishes a session for each link.
Prime Network Vision supports BFD with the following protocols: BGP, IPv4 (static), IPv6 (static),
IS-IS, LAG (Ether channel), MPLS TE, MPLS-TP, and OSPF.
To view BFD session properties that are configured on an element:
Step 1 In Prime Network Vision, double-click the required device.
Step 2 In the inventory window, choose Logical Inventory > Bidirectional Forwarding Detection.
The properties for BFD sessions are displayed as shown in Figure 18-19.

Addressing Protocol (ISATAP) address.
