Step 8
Enable BFD for IS-IS on an Interface
Perform the following steps to configure BFD for Integrated Intermediate System-to-Intermediate System
(IS-IS) on an interface.
BFD per interface configuration is supported for OSPF and IS-IS only.
Note
Router# configure
/* Enter IS-IS configuration mode to configure the IS-IS routing process. */
Router(config)# router isis 65444
/* Set the system type (area or backbone router). Each IS-IS instance can support either a
single Level 1 or Level 2, or one of each.*/
Router(config-isis)#is-type level-2-only
/* Specify a NET for each routing instance if you are configuring multi-instance IS-IS.*/
Router(config-isis)# net 49.0001.0840.3803.4088.00
/* Enter interface configuration mode. */
Router(config-isis)# interface gigabitEthernet 0/3/0/1
/* Set the BFD minimum interval. */
Router(config-isis-if)# bfd minimum-interval 4
/* Specify the IPv4 address family and enters router address family configuration mode. */
Router(config-isis)# address-family ipv4 unicast
/* Enable BFD to detect failures in the path between adjacent forwarding engines. Only IPv4
is supported.*/
Router(config-isis-if-af)# bfd fast-detect ipv4
