The following example available in Cisco IOS Release 12.0(32)SY8, 12.2(33)SXI1, 12.0(33)S3,
Cisco IOS XE Release 2.4, and later releases, shows how to create a VRF with a route-target that uses a
4-
byte autonomous system number in asplain format—65537—and how to set the route-target to
extended community value 65537:100 for routes that are permitted by the route map.
ip vrf vpn_red
rd 64500:100
route-target both 65537:100
exit
route-map red_map permit 10
set extcommunity rt 65537:100
end
After the configuration is completed, use the show route-map command to verify that the extended
community is set to the route target containing the 4-byte autonomous system number of 65537.
