RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#echo startup validate force
BFD Echo Mode Disable: Examples
The following example shows how to disable echo mode on a router:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:routerr(config-bfd)#echo disable
The following example shows how to disable echo mode on an interface:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#interface gigabitethernet 0/1/0/0
RP/0/RSP0/CPU0:router(config-bfd-if)#echo disable
BFD Dampening: Examples
The following example shows how to configure an initial and maximum delay for BFD session startup on
BFD bundle members:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#dampening bundle-member initial-wait 8000
RP/0/RSP0/CPU0:router(config-bfd)#dampening bundle-member maximum-wait 15000
The following example shows how to change the default initial-wait for BFD on a non-bundle interface:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#dampening initial-wait 30000
RP/0/RSP0/CPU0:router(config-bfd)#dampening maximum-wait 35000
BFD IPv6 Checksum: Examples
The following example shows how to disable IPv6 checksum calculations for UDP packets for all BFD
sessions on the router:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#ipv6 checksum disable
The following example shows how to reenable IPv6 checksum calculations for UDP packets for all BFD
sessions on the router:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
RP/0/RSP0/CPU0:router(config-bfd)#no ipv6 checksum disable
The following example shows how to enable echo mode for BFD sessions on an individual interface:
RP/0/RSP0/CPU0:router#configure
RP/0/RSP0/CPU0:router(config)#bfd
