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) > On 9 Feb 2024, at 11:05, o.evistel@xxxxxxx wrote: > > > Dear Marcelo > > I am using linux-sctp as transport for SIGTRAN M3UA on RHEL 8.4 with multihoming (sctp_bindx(), sctp_connectx() API functions). > I would like to know, after association setup, if it is possible to instruct SCTP to use a specific local address from the list of bound addresses to reach the peer. > > Regards > Omar AIT AMRANE >
