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