bfd multihop-peer dst-ip-address { authentication { md5 | meticulous-md5 | meticulous-sha1 plain-text | sha1 } { encrypted password-string | password password-string } | interval tx_interval min_rx rx_interval multiplier value }
Specifies the destination address of the BFD enabled peer in IPv4 dotted-decimal or IPv6 colon-separated notation. This destination address must have been previously configured via the ip route static bfd commands in the Context Configuration mode.

md5 – Message Digest 5
|
|
•
|
meticulous-md5 – MD5 using a secret key and sequence numbers updated for every packet
|
|
•
|
meticulous-sha1 – SHA1 with sequence numbers updated for every packet
|
|
•
|
plain-text – plain text (unencrypted)
|
|
•
|
sha1 – Secured Hash Algorithm 1
|
Specifies the password for authentication of BFD sessions. The password must be the same between the peer neighbors for the BFD sessions to work. If the authentication password is configured incorrectly between peers, the BFD sessions to the destination address will not come UP. If the password is configured for BFD sessions that are already UP, BFD neighbors will be reset.

|
encrypted password-string: Specifies the use of an encrypted password for authentication of BFD sessions as an alphanumeric string of up to 523 characters.
|
|
•
|
password password-string: Specifies the use of a plain text password for authentication of BFD sessions as an alphanumeric string of 1 through 19 characters.
|
Important: The destination address and its transmit/receive intervals must be configured before the password is applied to any MH-BFD sessions at a destination address.interval tx_interval: Specifies the transmit interval (in milliseconds) between BFD packets as an integer from 50 through 999. Default: 50
min_rx rx_interval: Specifies the receive interval (in milliseconds) between BFD packets as an integer from 50 through 999. Default: 50
multiplier value: Specifies the multiplier value sued to compute holddown as an integer from 3 through 50. Default: 3

active-if-name if-name: Specifies an active interface that notifies all passive interfaces in this group. There should be only one active interface in a group. if-name is a logical or physical interface specified as an alphanumeric string of 1 through 79 characters.
passive-if-name if-name: Specifies a passive interface that receives BFD notifications from the active interface in this group. if-name is a logical or physical interface specified as an alphanumeric string of 1 through 79 characters.
