Exporting An Inactive Bgp Route From A Vprn - Alcatel-Lucent 7450 Configuration Manual

Exporting an Inactive BGP Route from a VPRN

The export-inactive-bgp command under config>service>vprn introduces an IP VPN
configuration option that allows the best BGP route learned by a VPRN to be exported as a VPN-
IP route even when that BGP route is inactive due to the presence of a more preferred BGP-VPN
route from another PE. This "best-external" type of route advertisement is useful in active/standby
multi-homing scenarios because it can ensure that all PEs have knowledge of the backup path
provided by the standby PE.
