+Subject: [PATCH 1/2] bgpd: Fix `no set as-path prepend ASNUM...`
+
+If entering `no set as-path prepend 1 2 3`, it's warned as unknown command.
+
+Now fixed, and the following combinations work fine:
+
+```
+no set as-path prepend
+no set as-path prepend last-as
+no set as-path prepend last-as 1
+no set as-path prepend 1
+no set as-path prepend 1 2
+```
+
+Fixes: https://github.com/FRRouting/frr/issues/15912
