Usage guidelines An IPv6 static route that has the destination address configured as ::/0 (a prefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packet does not match any entry in the routing table, this default route is used to forward the packet. If the output interface is an NBMA interface or broadcast interface (such as a VLAN interface), the next hop address must be specified. Follow these guidelines when you configure a static route: • Enabling BFD for a flapping route could worsen the 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. • Do not specify the permanent keyword together with the bfd or track keyword.

Usage guidelines
An IPv6 static route that has the destination address configured as
::/0
(a prefix length of 0) is the default
IPv6 route. If the destination address of an IPv6 packet does not match any entry in the routing table, this
default route is used to forward the packet.
If the output interface is an NBMA interface or broadcast interface (such as a VLAN interface), the next
hop address must be specified.
Follow these guidelines when you configure a static route:
Enabling BFD for a flapping route could worsen the 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.
Do not specify the
permanent
keyword together with the
bfd
or
track
keyword.
Examples
# Configure an IPv6 static route, with the destination address 1:1:2::/64 and next hop 1:1:3::1.
