# On Router A, create an IPv6 prefix list prefix-to-b that permits subnet 11::0/64. Router A uses
this list to filter FEC-label mappings advertised to Router B.

# On Router A, create an IP prefix list peer-b that permits 2.2.2.9/32. Router A uses this list to
filter peers.

# On Router A, configure an IPv6 label advertisement policy to advertise only the label mapping
for FEC 11::0/64 to Router B.

# On Router D, configure an IPv6 label advertisement policy. This policy ensures that Router D
does not advertise label mappings for FEC 21::0/64 to Router A, and does not advertise label
mappings for FEC 11::0/64 to Router C.
