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 tha n one l ink exist s, 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.
Prefix Length IPv4 prefix length used to derive the delegated IPv6 prefix.
Suffix Length IPv4 suffix length used to derive the delegated IPv6 prefix.
MTU Maximum transmission unit (MTU) configured on the 6rd IPv4
tunnel.
