bfd
Syntax bfd transmit-interval [receive receive-interval] [multiplier multiplier] [echo-receive echo-
interval] [type cpm-np]
no bfd
Context config>service>vprn>interface
Description This command specifies the BFD parameters for the associated IP interface. If no parameters are
defined the default value are used.
The multiplier specifies the number of consecutive BFD messages that must be missed from the peer
before the BFD session state is changed to down and the upper level protocols (OSPF, IS-IS, BGP or
PIM) is notified of the fault.
The no form of the command removes BFD from the associated IGP protocol adjacency.
Important notes: On the 7750-SR, the transmit-interval, receive receive-interval, and echo-receive
echo-interval values can only be modified to a value less than 100 when:
1. The type cpm-np option is explicitly configured.
2. The service is shut down (shutdown)
3. The interval is specified 10 — 100000.
4. The service is re-enabled (no shutdown)
To remove the type cpm-np option, re-issue the bfd command without specifying the type
parameter.
Default no bfd
