Step 5 Verify the configuration.
# Run the display ipv6 routing-table 2001:db8:4::1 120 command on Router S to check the
IPv6 routing table. You can view that the next hop address is 2001:2 and the outbound interface
is Gigabit Ethernet 1/0/0.

As shown in the IPv6 routing table, after the primary path fails, the backup path takes effect; the
next hop address of the route to 2001:db8:4::/120 becomes 2001:db8:2::2; the outbound interface
becomes Gigabit Ethernet 2/0/0; the route cost may also change.
# Run the display isis ipv6 bfd session all command on Router S, and you can view that there
is only one BFD session in the Up state between Router S and Router N.
