Adding an address family to an existing session requires bouncing it as address family capabilities are negotiated upon session establishment. There is draft-ietf-idr-dynamic-cap which would avoid the reset, but this isn't implemented yet. And we have BGP multi-session so you build one session per AF, which would also avoid session resets. But I guess both are no options for you, so you would need to do it in a maintenance window if the session bounce has an impact. oli _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
