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

27.7 neighbor as-origination-interval
