•
If the output interface is a P2P interface, you can specify only the output interface. You do not
need to change the configuration of the route even if the peer address is changed.
Follow these guidelines when you configure BFD for IPv6 static routes:
•
If you specify a non-P2P output interface and a direct next hop, specify the
ipv6-address
meets the following requirements:
The address is the same as the IPv6 address of the output interface.

The address is on the same network segment as the next hop IPv6 address of the same

type.
For example, if the next hop IPv6 address is a link-local address, the source IPv6 address of
BFD packets must also be a link-local address.
•
If you specify the source IPv6 address of BFD packets, you must specify the IPv6 address as
the next hop IPv6 address on the peer device.
•
Enabling BFD for a flapping route could worsen the route flapping situation. Therefore, use it
with caution. For more information about BFD, see High Availability Configuration Guide.
•
The next hop IPv6 address of echo packets must be a global unicast address.
•
You cannot specify both the
For static routing-Track-NQA collaboration, you must configure the same VPN instance ID for the
next hop to be detected and the NQA operation.
If you do not specify the
preferentially recurses the IPv6 static route to a direct route. If no matching direct route is found, the
device performs IPv6 static route recursion based on the longest match principle. When recursing
the IPv6 static route to a direct route, the device takes the next hop of the IPv6 static route as directly
connected. In fact, the next hop might be incorrect and packets might fail to be forwarded based on
the IPv6 static route.
If you specify the
static route recursion based on the longest match principle to make sure that the next hop is correct.
Examples
# Configure an IPv6 static route in VPN instance vpn1, whose destination address is 1:1:2::/64 and
next hop address is 1:1:3::1 in VPN instance vpn2.
