160
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).
Examples
# In BGP view, reference ACL 2000 to filter all outgoing routes.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] filter-policy 2000 export
# In BGP-VPN instance view, reference ACL 2000 to filter all outgoing routes. (The VPN has been
created.)
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family vpn-instance vpn1
[Sysname-bgp-ipv4-vpn1] filter-policy 2000 export
# Configure ACL 3000 to permit only route 113.0.0.0/16 to pass, and reference ACL 3000 to filter
outgoing routes.
<Sysname> system-view
[Sysname] acl number 3000
[Sysname-acl-adv-3000] rule 10 permit ip source 113.0.0.0 0 destination 255.255.0.0 0
[Sysname-acl-adv-3000] rule 100 deny ip
[Sysname-acl-adv-3000] quit
[Sysname] bgp 100
