Configuration Example: Single-Hop Static BFD Session for a LAG
The following figure shows a single-hop
static BFD session for a LAG interface. BFD can monitor the next hop. Micro-BFD is
also
configured. All LAG member links are directly connected between two session endpoints.
The following configuration example configures a single-hop static BFD session for a LAG interface, as illustrated in the preceding figure. Router 1 has a static route to 10.20.20.20/24 with the next hop as 10.0.0.2/24. Router 2 has a static route to 10.10.10.10/24 with the next hop as 10.0.0.1/24. BFD session parameters are also configured. Micro-BFD is enabled.
