Since destination may have 1 or 2 elements I think that the following will be enough. struct { RouteMode routemode; OverlayLink transport; IpAddressPort ipaddressport; Destination destination<1..2^8-1>; } ExtensiveRoutingModeOption Regards Roni > -----Original Message----- > From: [email protected] [mailto:[email protected]] On > Behalf Of st?phane bryant > Sent: Wednesday, August 31, 2011 10:46 AM > To: [email protected] > Subject: [P2PSIP] structure definition issue in draft-zong-p2psip-drr- > 00 > > Hello, > > In draft-zong-p2psip-drr-00, section 6.2.2.
