.BR charon.ignore_routing_tables
A space-separated list of routing tables to be excluded from route lookups
.TP
+.BR charon.ike_fragmentation " [no]"
+Enables IKE fragmentation (proprietary IKEv1 extension). Fragmented messages
+are always accepted irrespective of the value of this option. If the peer
+supports it larger messages will be sent in fragments.

Number of exclusively locked segments in the hash table
