Hi, We have a setup that currently uses a local bridge domain on asr9k, one local physical interface and a number of P2P PWE3 that terminate on PWHE on other asr9ks. The setup is used for broadband termination. The P2P PWE3 go to BNGs. The main reason for using a bridge domain with multiple PWE3 so we can load-balance the subscribers among larger number of BNGs but also to provide more graceful fail-over to what can be achieved with a backup PWE3.
Currently the bridge domain learns MAC addresses, but as the number of subscriber grows that's likely to become a limiting factor. In reality we need something like an e-tree where the BNGs are the leafs and the physical interface is the root but with limited MAC address learning. In fact what all we need is one MAC address per BNG plus a 'default route' that points to the physical interface. Is there a way to define something like that? kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
