To specify an IPv6 prefix list called filterOspfRoutes that denies route 2001:db8:2::/64, enter the
following commands.
device(config)# ipv6 prefix-list filterOspfRoutes seq 5 deny 2001:db8:2::/64
device(config)# ipv6 prefix-list filterOspfRoutes seq 7 permit ::/0 ge 1 le 128
Syntax: ipv6 prefix-list name [seq seq-value] [description string] {deny | permit} ipv6-addr/mask-bits
[ge ge-value] [ le le-value]
To configure a distribution list that applies the filterOspfRoutes prefix list globally.
device(config)# ipv6 router ospf
device(config-ospf6-router)# distribute-list prefix-list filterOspfRoutes in
Syntax: [no] distribute-list prefix-list name in [ethernet slot/port | ve num | loopback num]
After this distribution list is configured, route 2001:db8:2::/64 would be omitted from the OSPFv3 route
table.

The following commands specify an IPv6 prefix list called filterOspfRoutesVe that denies route
2001:db8:3::/64.
device(config)# ipv6 prefix-list filterOspfRoutesVe seq 5 deny 2001:db8:3::/64
device(config)# ipv6 prefix-list filterOspfRoutesVe seq 10 permit ::/0 ge 1 le 128
The following commands configure a distribution list that applies the filterOspfRoutesVe prefix list to
routes pointing to virtual interface 10.
device(config)# ipv6 router ospf
device(config-ospf6-router)# distribute-list prefix-list filterOspfRoutesVe in ve 10
After this distribution list is configured, route 2001:db8:3::/64, pointing to virtual interface 10, would be
omitted from the OSPFv3 route table.
