Defining apply Clauses
for the Routing Policy
To do...
Match routes having the specified route type
Match RIP, OSPF, or IS-IS routes having the
specified tag value
The if-match clauses of a route-policy are in logic AND relationship, namely,
■
routing information has to satisfy all if-match clauses before being executed
with apply clauses.
You can specify no or multiple if-match clauses for a routing policy. If no
■
if-match clause is specified, and the routing policy is in permit mode, all
routing information can pass the node; if in deny mode, no routing
information can pass.
Follow these steps to define apply clauses for a route-policy:
To do...
Enter system view
Create a routing policy and
enter its view
Set AS_Path attribute for BGP
routes
Specify a community list
according to which to delete
community attributes of BGP
routing information
Set community attribute for
BGP routes
Set a cost for routes
Set a cost type for routes
Set the extended community
attribute for BGP routes
Configuring a Routing Policy
Use the command...
if-match route-type
{ internal |
external-type1 |
external-type2 |
external-type1or2 |
is-is-level-1 |
is-is-level-2 |
nssa-external-type1 |
nssa-external-type2 |
nssa-external-type1or2
} *
if-match tag value
Use the command...
system-view
route-policy route-policy-name
{ permit | deny } node
node-number
apply as-path
as-number&<1-10> [ replace ]
apply comm-list
comm-list-number delete
apply community { none |
additive |
{ community-number&<1-16> |
aa:nn&<1-16> | internet |
no-export-subconfed |
no-export | no-advertise } *
[ additive ] }
apply cost [ + | - ] value
apply cost-type [ external |
internal | type-1 | type-2 ]
apply extcommunity { rt
{ as-number:nn |
ip-address:nn } }&<1-16>
[ additive ]
