Single-hop echo mode
With BFD echo mode enabled for a static route, the output interface sends BFD echo packets to the
destination device, which loops the packets back to test the link reachability.
IMPORTANT:
Do not use BFD for a static route with the output interface in spoofing state.
To configure BFD echo mode for an IPv6 static route:

Command Remarks
1. Enter system view.
system-view N/A
2. Configure the source
address of echo
packets.
bfd echo-source-ipv6 ipv6-address
By default, the source address
of echo packets is not
configured.
The source address of echo
packets must be a global
unicast address.

Reference.
3. Configure BFD echo
mode for an IPv6
static route.
• Method 1:
ipv6 route-static ipv6-address prefix-length
interface-type interface-number
next-hop-address bfd echo-packet
[ preference preference-value ] [ tag
tag-value ] [ description description-text ]
• Method 2:
ipv6 route-static vpn-instance
s-vpn-instance-name ipv6-address
prefix-length interface-type
interface-number next-hop-address bfd
echo-packet [ preference preference-value ]
[ tag tag-value ] [ description
description-text ]
Use either method.
By default, BFD echo mode for
an IPv6 static route is not
configured.
The next hop IPv6 address must
be a global unicast address.
