  "message": "bgpd: add replace-as modifier for BGP neighbor\n\nAdded replace-as modifier for BGP neighbors when using\nlocal-as. If the replace-as modifier is specified, only the\nreplacement AS as specified by the local-as modifier is\nprepended to the AS_PATH, not the process\u0027s AS.\n\nIn bgp_attr.c, I decided that\n\nif (peer-\u003echange_local_as) {\n  /* If replace-as is specified, we only use the change_local_as when\n     advertising routes. */\n  if( ! CHECK_FLAG (peer-\u003eflags, PEER_FLAG_LOCAL_AS_REPLACE_AS) ) {\n    aspath \u003d aspath_add_seq (aspath, peer-\u003elocal_as);\n  }\n  aspath \u003d aspath_add_seq (aspath, peer-\u003echange_local_as);\n} else {\n  aspath \u003d aspath_add_seq (aspath, peer-\u003elocal_as);\n}\n\nwas clearer than the alternative that didn\u0027t duplicate the prepending of the\nprocess\u0027s AS:\n\n/* First, append the process local AS unless we have an alternate local_as\n * and we\u0027re replacing it (as opposed to just prepending it). */\nif (!
