197Use undo bfd echo-source-ip to remove the configured source IP address of BFD echo packets.Since a large amount of ICMP redirect packets might be sent by the remote switch, causing networkcongestion, do not configure the source IP address of the BFD echo packets to belong to the samenetwork segment as any interface address of the switch.Examples# Configure the source IP address of echo packets as 10.1.1.1. system-view[Sysname] bfd echo-source-ip 10.1.1.1bfd min-echo-receive-intervalSyntaxbfd min-echo-receive-interval valueundo bfd min-echo-receive-intervalViewInterface viewDefault level2: System levelParametersvalue: Minimum echo receiving interval, in milliseconds. The value range and default value depend onthe main processing unit (MPU) model of the switch:• For switches with MPU LSR1SRP2D1, LSR1SRP2C1, or LSR1SRP2C2, the value is in the range of 10to 1000, and must be a multiple of 10. The default value is 400.• For switches with MPU LSR1SRP2B1 or LSR1SRP2B2, the value is in the range of 1000 to 10000,and must be a multiple of 100. The default value is 1000.DescriptionUse bfd min-echo-receive-interval to configure the minimum echo packet receiving interval on theinterface.Use undo bfd min-echo-receive-interval to restore the default.By default, the minimum BFD echo packet receiving interval on the interface is 400 milliseconds.Examples# Configure the minimum echo receiving interval on VLAN-interface 1 as 500 milliseconds. system-view[Sysname] interface vlan-interface 1[Sysname-Vlan-interface1] bfd min-echo-receive-interval 500bfd min-receive-intervalSyntaxbfd min-receive-interval valueundo bfd min-receive-interval
