Configuration Example: BFD for OSPF Single-Hop Session for an Ethernet Interface
The following figure shows a BFD single-hop session that is configured for OSPFv2
for Ethernet interface 1/1/1 on two devices, Router 1 and Router2.
The following configuration configures a BFD single-hop session for OSPFv2, as illustrated in the preceding figure. BFD for OSPFv2 is configured for Ethernet interface 1/1/1 on both Router 1 and Router 2. The BFD session parameters are also configured.
