Page 171 highlights

If no routing protocol is specified, all outgoing routes are filtered. By default, no route filtering is configured. If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, 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 and the destination keyword specifies the subnet mask of the route (the subnet mask must be valid; otherwise, the configuration is ineffective).

If no routing protocol is specified, all outgoing routes are filtered.
By default, no route filtering is configured.
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, 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 and the
destination
keyword specifies the subnet mask of the route (the subnet mask must be valid;
otherwise, the configuration is ineffective).
