The system view is displayed.
Step 2
Run:
rip
[
process-id
]
The RIP process is enabled and the RIP view is displayed.
Step 3
Depending on type of desired filtering, run one of following commands to configure RIP to filter
the received routes:
l
Based on the basic ACL:
1.
Run
filter-policy
{
acl-number
|
acl-name
acl-name
}
import
, the learned routing
information is filtered based on an ACL.
2.
Run
quit
, return to the system view.
3.
Run
acl
{ [
number
]
acl-number1
|
name
acl-name
basic
[
number
acl-number2
] }
[
match-order
{
auto
|
config
} ], the basic ACL view is displayed.
4.
Run
rule
[
rule-id
] {
deny
|
permit
} [
fragment-type
fragment-type-name
|
source
{
source-ip-address source-wildcard
|
any
} |
time-range
time-name
|
vpn-instance
vpn-instance-name
]
*
, a rule is configured for the basic ACL.
When a filtering policy of a routing protocol is used to filter routes:
–
If the action specified in an ACL rule is
permit
, a route that matches the rule will
be received or advertised by the system.
–
If the action specified in an ACL rule is
deny
, a route that matches the rule will not
be received or advertised by the system.
–
If a route has not matched any ACL rules, the route will not be received or advertised
by the system.
–
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.
l
Based on the named advanced ACL:
1.
Run
filter-policy
acl-name
acl-name
import
, the learned routing information is filtered
based on an ACL.
2.
Run
quit
, return to the system view.
3.
Run
acl
name
acl-name
advance
[
number
acl-number2
] [
match-order
{
auto
|
config
} ], the basic ACL view is displayed.
