Layer 3 Routing Commands 1331
• import —Imports routing information from the target VPN extended
community.
• both—Exports and imports the routing information to/from the target
VPN extended community.
•
rt-ext-comm — The route-target extended community attributes to be
added to the list of import, export or both (import and export) route-target
extended communities.
The route target specifies a target VPN extended community. Like a route
distinguisher, the route-target extended community can be specified in
either of the following formats:
• 16-bit AS number :your 32-bit value (Ex : 100:11)
• 32-bit IPv4 address :your 16-bit value (Ex : 10.1.1.1:22)
Default Configuration
No route targets are configured by default.
Command Mode
Privileged Exec mode
User Guidelines
Configure the route-target command once for each target extended
community. Routes that are learned and carry a specific route-target
extended community are imported into all VRFs configured with that
particular extended community as an import route target.
The configured export RT is advertised as an extended community in the MP-
BGP format to the eBGP peer. An RT is either:
• ASN related – Composed of an autonomous system number and an
arbitrary number.
• IP address related – Composed of an IP address and an arbitrary number.
This command is effective only if BGP is running on the router.
Command History
Introduced in version 6.3.0.1 firmware.
