Due to this limitation, data center deployments are forced to use public ASNs in their private networks. When such private networks are interconnected to each other, there needs to be a way to manipulate the public ASNs in the route advertisements so that the private networks with the public ASNs don't experience ASN conflicts. With the options no-prepend and replace-as • The router replaces the global AS of the router with the configured local-as when advertising the routes to the peer on which this command is configured. • As well the local-as is not prepended to the routes received from the neighbor on which this command is configured. This command is allowed only on external BGP neighbors. A neighbor can inherit this configuration from a peer template. When the local-as is configured for a peer, the BGP peer adjacency gets reset. Command History Introduced in version 6.3.0.1 firmware. Command updated in version 6.6 firmware. Command mode updated in version 6.8 firmware. Example console(config)#router bgp 65000 console(config-router)# neighbor 172.20.1.2 remote-as 65001 console(config-router)# neighbor 172.20.1.2 local-as 65002 no-prepend replace-as console(config-router)# neighbor 2001::2 remote-as 65003 console(config-router)# neighbor 2001::2 local-as 65002 no-prepend replaceas neighbor maximum-prefix (BGP Router Address Family) In IPv6 address family configuration mode, the neighbor maximum-prefix command specifies the maximum number of IPv6 prefixes that BGP will accept from a given neighbor.
