Command History
Usage Guidelines The SoO extended community is a BGP extended community attribute that is used to identify routes that
h
ave originated from a site so that the re-advertisement of that prefix back to the source site can be
prevented. The SoO extended community attribute uniquely identifies the site from which a PE router
has learned a route.
Examples The following example configures SoO filtering on an interface:
Router(config)# route-map Site-of-Origin permit 10
Router(config-route-map)# set extcommunity soo 100:1
Router(config-route-map)# exit
Router(config)# interface FastEthernet 0/0
Router(config-if)# ip vrf forwarding RED
Router(config-if)# ip vrf sitemap Site-of-Origin
Router(config-if)# ip address 10.0.0.1 255.255.255.255
Router(config-if)# end
