Usage
In a hub and spoke configuration, a PE router re-advertises all prefixes containing duplicate ASNs. Use the
neighbor allowas-in command to configure two VRFs on each PE router to receive and re-advertise prefixes.
One of the VRFs receives prefixes with ASNs from all PE routers and then advertises them to neighboring PE
routers. The other VRF receives prefixes with ASNs from the CE router and re-advertises them to all PE
routers in the hub and spoke configuration.
Control the number of times an ASN is advertised, by specifying a number from 1 to 10.
Examples
Switch(config-router)# address-family ipv4 vrf VRF_A
Switch(config-router-af)# neighbor 10.10.0.1 allowas-in 3
