+Subject: [PATCH] nest/config.Y: fix build without babel, bgp, ospf, radv, rip
+ or static
+
+Build without babel, bgp, ospf, radv, rip or static fails on:
+
+bison  -Dparse.lac=full -Dparse.error=verbose -dv -pcf_ -b
+obj/conf/cf-parse obj/conf/cf-parse.y
+nest/config.Y:381.20-23: error: symbol LINK is used, but is not
+defined as a token and has no rules
+  381 |  | dev_proto CHECK LINK bool ';' { DIRECT_CFG->check_link = $4; }
+      |                    ^~~~
+make[1]: *** [obj/conf/cf-parse.tab.c] Error 1
+
+This error is raised because of the following commit:
+https://gitlab.labs.nic.cz/labs/bird/commit/e90dd656cc9126e1fbcc45fb77a10bf1baa2a1b5
+
+This commit assumes that LINK is defined which is not always the case.
+Indeed, it seems that LINK is not defined by BFD, MRT, PERF, PIPE, RPKI
+
+To fix this issue, add CF_KEYWORDS(LINK) in nest/config.py
+
