ip-prefix ip-prefix-name
: Name of an IP address prefix list used to filter incoming routes based on
destination IP address, a string of up to 19 characters. For details about IP prefix lists, see
Route
Policy Configuration
in the
Layer 3 - IP Routing Configuration Guide
.
route-policy
route-policy-name
: Name of a route policy used to filter incoming routes based on route
policy, a string of up to 19 characters. For details about route policy, see
Route Policy Configuration
in
the
Layer 3 - IP Routing Configuration Guide
.
Description
Use the
filter-policy import
command to configure the filtering of routes calculated from received
LSAs.
Use the
undo filter-policy import
command to disable the filtering.
By default, the filtering is not configured.
Note that if you want to reference an advanced ACL (with a number from 3000 to 3999) in the
command or in the route policy, the ACL should be configured with the
rule
[
rule-id
] {
deny
|
permit
}
ip source
sour-addr sour-wildcard
command to deny/permit a route with the specified destination, or
with the
rule
[
rule-id
] {
deny
|
permit
}
ip source
sour-addr sour-wildcard
destination
dest-addr
dest-wildcard
command to deny/permit a route with the specified destination and mask. The
source
keyword specifies the destination address of a route while the
destination
keyword specifies the
subnet mask of the route (the subnet mask must be valid; otherwise, the configuration is ineffective).
