rt  route-target: Sets the route target extended community attribute, which is a string of 3 to 21 

characters. A route-target has two forms:  

16-bit AS number: 32-bit self-defined number, for example, 101:3; 

32-bit IP address: 16-bit self-defined number, for example, 192.168.122.15:1. 

&<1-16>: Indicates the argument before it can be entered up to 16 times. 

additive: Adds the specified attribute to the original RT community attribute.  

Use the apply extcommunity command to apply the specified RT extended community attribute to 

BGP routes.  

Use the undo apply extcommunity command to remove the clause configuration.  

No RT extended community attribute is set for BGP routing information by default. 

# Configure node 10 in permit mode of route policy policy1: If a BGP route matches AS-PATH list 1, add 

the RT extended community attribute 100:2 to the route.
