We are trying to connect two links on a router using two autonomous systems simultaneously, but we can only get one connection to work and not both at the same time. Does anyone know if a license is needed to support multiple AS systems? If so, what license do we need?
Thanks

On a router, if a prefix is learned by 2 differrent EIGRP processes (2 differrent EIGRP ASs) , only one can be installed in that router's routing table.

Hello @BandaM ,
as it has been explained by @nguyenbmt106 , two different EIGRP AS numbers / processes are "ships in the night" each of them attempt to provides prefixes to the routing table but load balancing is not supported in this scenario, if all parameters are the same AD and metric the process with lowest ASN is the one that installs the route in the IP routing table.
it is not a licensing issue but a known behaviour.
Hope to help
Giuseppe
