Configuring apply clauses
Except for the apply commands used for setting the next hop for IPv4 and IPv6 routes, all apply commands are the same for IPv4 and IPv6 routing.
To configure apply clauses:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter routing policy node view. | route-policy route-policy-name { deny | permit } node node-number | N/A |
3. Set the AS_PATH attribute for BGP routes. | apply as-path as-number&<1-32> [ replace ] | By default, no AS_PATH attribute is set for BGP routes. |
4. Delete the specified COMMUNITY attribute for BGP routes. | apply comm-list { comm-list-number | comm-list-name } delete | By default, no COMMUNITY attribute is deleted for BGP routes. |
5. Set the specified COMMUNITY attribute for BGP routes. | apply community { none | additive | { community-number&<1-32> | aa:nn&<1-32> | internet | no-advertise | no-export | no-export-subconfed } * [ additive ] } | By default, no community attribute is set for BGP routes. |
6. Set a cost for routes. | apply cost [ + | - ] value | By default, no cost is set for routes. |
7. Set a cost type for routes. | apply cost-type { external | internal | type-1 | type-2 } | By default, no cost type is set for routes. |
8. Set the extended community attribute for BGP routes. | apply extcommunity { rt route-target }&<1-32> [ additive ] | By default, no extended community attribute is set for BGP routes. |
9. Set the next hop for routes. |
| By default, no next hop is set for IPv4/IPv6 routes. The apply ip-address next-hop and apply ipv6 next-hop commands do not apply to redistributed IPv4 and IPv6 routes. |
10. Redistribute routes to a specified ISIS level. | apply isis { level-1 | level-1-2 | level-2 } | By default, routes are not redistributed into a specified IS-IS level. |
11. Set a local preference for BGP routes. | apply local-preference preference | By default, no local preference is set for BGP routes. |
12. Set MPLS labels. | apply mpls-label | By default, no MPLS label is set. |
13. Set the ORIGIN attribute for BGP routes. | apply origin { egp as-number | igp | incomplete } | By default, no ORIGIN attribute is set for BGP routes. |
14. Set a preference. | apply preference preference | By default, no preference is set. |
15. Set a preferred value for BGP routes. | apply preferred-value preferred-value | By default, no preferred value is set for BGP routes. |
16. Set a prefix priority. | apply prefix-priority { critical | high | medium } | By default, no prefix priority is set, which means the prefix priority is low. |
17. Set a tag value for RIP, OSPF, and IS-IS route. | apply tag value | By default, no tag value is set for RIP, OSPF, and IS-IS routes. |
18. Set a backup link for fast reroute (FRR). | apply fast-reroute backup-interface interface-type interface-number [ backup-nexthop ip-address ] | By default, no backup link is set for FRR. |
