Re: Linux SCTP multihoming question

Hi Andreas,

My explanation was not clear enough.

I would like to know if it is possible to force sctp to use alernate address instead of primary address while both of them are available.

Regards
Omar

yes this is possible. My eSTP does this exactly this way. for M3UA and M2PA You simply use sctp_bindx to bind to exact local address you need.
You can add or remove local IP's and alter the association. But I'm not sure if you can force a specific path to be used as primary. SCTP basically can use any and switch over to the other.

If you think of something like hot/standby setup, you might want to do this on M3UA level which means having two SCTP associations (two ASPs in one AS)
