Changes keyword 'exceed' to 'action'.

	uses global router id.

	<tag>import all | none | filter <m/name/ | filter { <m/filter commands/ } | where <m/filter expression/</tag> 

	Specify a filter to be used for filtering routes coming from the protocol to the routing table. <cf/all/ is shorthand for <cf/where true/ and <cf/none/ is shorthand for <cf/where false/. Default: <cf/all/.

	Specify a filter to be used for filtering routes coming from

	the protocol to the routing table. <cf/all/ is shorthand for

	<cf/where true/ and <cf/none/ is shorthand for

	<cf/where false/. Default: <cf/all/.

	<tag>export <m/filter/</tag> This is similar to the <cf>import</cf> keyword, except that it

	works in the direction from the routing table to the protocol. Default: <cf/none/.

	<tag>export <m/filter/</tag>

	This is similar to the <cf>import</cf> keyword, except that it

	works in the direction from the routing table to the protocol.

	Default: <cf/none/.

	<tag>import limit <m/number/ [exceed warn | block | restart | disable]</tag>

	<tag>import limit <m/number/ [action warn | block | restart | disable]</tag>

	Specify an import route limit (a maximum number of routes

	imported from the protocol) and optionally the action to be

	taken when the limit is hit. Warn action just prints warning

	log message. Block action ignores new routes coming from the

	protocol. Restart and disable actions shut the protocol down

	like appropriate commands. Disable is the default action if an

	action is not explicitly specified.  Default: <cf/none/.

	action is not explicitly specified. Note that limits are reset

	during protocol reconfigure, reload or restart.

	Default: <cf/none/.

	<tag>export limit <m/number/ [exceed warn | block | restart | disable]</tag>

	<tag>export limit <m/number/ [action warn | block | restart | disable]</tag>

	Specify an export route limit, works similarly to

	the <cf>import limit</cf> option, but for the routes exported

	to the protocol. This option is experimental, there are some
