– If an ACL does not contain any rules, all routes matching the route-
policy that references the ACL will not be received or advertised by
the system.
– If the ACL referenced by the route-policy does not exist, all routes
matching the route-policy will be received or advertised by the
system.
– In the configuration order, the system first matches a route with a rule
that has a smaller number and then matches the route with a rule with
a larger number. Routes can be filtered using a blacklist or a whitelist:
Route filtering using a blacklist: Configure a rule with a smaller
number and specify the action deny in this rule to filter out the
unwanted routes. Then, configure another rule with a larger number in
the same ACL and specify the action permit in this rule to receive or
advertise the other routes.
Route filtering using a whitelist: Configure a rule with a smaller
number and specify the action permit in this rule to permit the routes
to be received or advertised by the system. Then, configure another
rule with a larger number in the same ACL and specify the action
deny in this rule to filter out unwanted routes.
– ipv6 filter-policy ipv6-prefix ipv6-prefix-name export [ protocol [ process-id ] ]
IS-IS is configured to advertise specified external routes to the IS-IS routing
domain based on the prefix list.
– ipv6 filter-policy route-policy route-policy-name export [ protocol [ process-
id ] ]
IS-IS is configured to advertise specified external routes to the IS-IS routing
domain based on the route policy.
NOTE
After this command is run, only external routes that meet the specified conditions can be
advertised to the IS-IS routing domain.

information.
