BFD Configuration Examples

In this section:

  1. 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.
  2. Configuration Example: Single-Hop Session for One Member Link for a LAG
    The following figure shows a single-hop static BFD session for one member link for a LAG interface. Micro-BFD is not configured because the LAG member links are not directly connected between two session endpoints. A single BFD session is configured for the LAG interface.
  3. 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.
  4. Configuration Example: BFD for OSPF Single-Hop Session for a LAG Interface
    The following figure shows a BFD single-hop session that is configured for OSPFv2 for a LAG interface on two devices, Router 1 and Router 2. Micro-BFD is also configured for the LAG interface. All LAG member links are directly connected between two session endpoints.
  5. Configuration Example: BFD for OSPF Single-Hop Session for a VE Interface
    The following figure shows a BFD single-hop session that is configured for OSPFv2 for a Virtual Ethernet (VE) interface on a LAG on two devices, Router 1 and Router 2. A single-hop BFD session is configured and micro-BFD is enabled.
  6. Configuration Example: BFD for eBGP Single-Hop Session
    The following figure shows a BFD single-hop session that is configured for eBGP for Ethernet interface 1/1/1 on two devices, Router 1 and Router 2.
  7. Configuration Example: BFD for iBGP Single-Hop Session
    The following figure shows a BFD session configured for iBGP for Ethernet interface 1/1/1 on two devices, Router 1 and Router 2.
  8. Configuration Example: BFD for IP Static Routes Single-Hop Session
    The following figure shows a single-hop static BFD session. BFD can monitor the next hop.
  9. Configuration Example: BFD for IP Static Routes Multi-hop Session
    The following figure shows a multi-hop static BFD session.
