Quick Steps for Configuring BFD

Configuring BFD involves:

• Optional: Configuring BFD explicitly on the IP interfaces.

• Configuring Layer 3 protocols to use BFD (see “Quick Steps for Configuring BFD Support for Layer 3

Protocols” on page 20-6).

If BFD is not explicitly configured, the default BFD global session parameters (transmit, receive and echo

intervals) are applied to the BFD sessions.

The following steps provide a brief tutorial for configuring a BFD session and related parameters:

1 Configure a BFD session on an IPv4 or IPv6 interface using the ip|ipv6 bfd interface command. For

example:

-> ip bfd interface bfd_int_1

-> ipv6 bfd interface bfd_int_2

2 Optional: Configure a global transmit time interval for all BFD sessions using the ip bfd transmit

command. This command defines a default transmit value that is automatically applied when a BFD

session is created. For example:

-> ip bfd transmit 500

3 Optional: Configure the transmit time interval for a specific BFD session using the ip|ipv6 bfd

interface transmit command. The value set with this command overrides the global transmit value

configured for the routing instance. For example:

-> ip bfd interface bfd-vlan-101 transmit 500

-> ipv6 bfd interface bfd-vlan-201 transmit 500

4 Optional: Configure a global receive time interval for all BFD sessions using the ip bfd receive

command. This command defines a default receive time value that is automatically applied when a BFD

session is created. For example:

-> ip bfd receive 500

5 Optional: Configure the receive time interval for a specific BFD session using the ip|ipv6 bfd

interface receive command. The value set with this command overrides the global receive time value

configured for the routing instance:

-> ip bfd interface bfd-vlan-101 receive 500

-> ipv6 bfd interface bfd-vlan-201 receive 500

6 Optional: Configure a global detection time multiplier value for all BFD sessions using the ip bfd

multiplier command. For example:

-> ip bfd multiplier 5

Note. Configuring a BFD session explicitly with an IP interface name is optional, and must be used if user-

defined BFD session parameters need to be applied. All the steps for explicit configuration are mentioned

as optional.
