Set the minimum interval after
which the neighbor should
generate BFD message.
On the interface
(optionally)
esr(config-if-gi)# ip
bfd min-rx-interval
<TIMEOUT>
<TIMEOUT> – interval after which the
BFD message should be sent by the
neighbor, takes values in milliseconds
in the range of [200..65535] for
ESR-1000/1200/1500/1700 and
[300..65535] for ESR-10/12V(F)/
20/21/100/200
By default:
300 ms on ESR-10/12V(F)/
14VF/20/21/100/200
200 ms on
ESR-1000/1200/1500/1700
12
Set the minimum interval after
which the BFD message is sent to
the neighbor.
On the interface
(optionally)
esr(config-if-gi)# ip
bfd min-tx-interval
<TIMEOUT>
<TIMEOUT> – interval after which the
BFD message should be sent by the
neighbor, takes values in milliseconds
in the range of [200..65535] for
ESR-1000/1200/1500/1700 and
[300..65535] for ESR-10/12V(F)/
20/21/100/200
By default:
300 ms on ESR-10/12V(F)/
14VF/20/21/100/200
200 ms on
ESR-1000/1200/1500/1700
13
Set the amount of dropped
packets, at which the BFD neighbor
is considered to be unavailable.
On the interface
(optional)
esr(config-if-gi)# ip
bfd multiplier <COUNT>
<COUNT> – amount of dropped
packets, at which the neighbor is
considered to be unavailable, takes
values in the range of [1..100].
Default: 5
14
Switch BFD session to the passive
mode, so that BFD messages will
not be sent until the messages
from BFD neighbor are received.
On the interface
(optionally)
esr(config-if-gi)# ip
bfd passive
