56: Notes:
57:
58: Export of routes to RS EBGP (route server) sessions from other sources than
59: RS EBGP sessions was changed that ASN is no longer prepended to BGP_PATH in
60: that case. The change does not affect regular BGP configurations or regular
61: route servers that have only RS EBGP peers.
62:
63: For BGP route servers and route reflectors, the default value of option
64: 'next hop keep' was changed to a more appropriate value.
65:
66: Attributes for OSPF and Babel metrics are no longer reset when exported to
67: these protocols and could be set anywhere in BIRD. As a result, OSPF metric is
68: kept when a route is reannounced between OSPF instances. Also, when route is
69: exported to OSPF with both ospf_metric1 and ospf_metric2 attributes it is now
70: propagated as OSPF-E2 route instead of as OSPF-E1 route.
71:
72: Compiling BIRD with --enable-debug no longer automatically activates debug
73: mode (-d option) nor local mode (-l option). Also, debug mode with output to
74: file (-D option) no longer not forces foreground mode (-f option).
75:
76: The configure script now uses standard option --runstatedir, the old option
77: --with-runtimedir is deprecated.
78:
79:
