NOTE
The apply comm-filter delete command deletes a specified community attribute from a
route. An instance of the ip community-filter command can specify only one community
attribute each time. To delete more than one community attribute, run the ip community-
filter command multiple times. If multiple community attributes are specified in one
community filter, none of them can be deleted. For more information, see the HUAWEI
NetEngine80E/40E Router Command Reference.
– To delete all community attributes from a BGP route, run the apply community
none command.
– To set community attributes for a BGP route, run the apply community
{ community-number | aa:nn | internet | no-advertise | no-export | no-export-
subconfed } &<1-32> [ additive ] command.
– To set an extended community attribute (route-target) for a route, run the apply
extcommunity { rt { as-number:nn | 4as-number:nn | ipv4-address:nn } }
&<1-16> [ additive ] command.
– To set the local preference for a BGP route, run the apply local-preference
preference command.
– To set the Origin attribute for a BGP route, run the apply origin { igp | egp { as-
number-plain | as-number-dot } | incomplete } command.
– To set a preferred value for a BGP route, run the apply preferred-value preferred-
value command.
– To set dampening parameters for an EBGP route, run the apply dampening half-
life-reach reuse suppress ceiling command.
The operations in Step 4 can be performed in any order. A node may have multiple
apply clauses or no apply clause.
