of ``0.0.0.0`` / ``::``. This can be useful to constrain bgpd to an internal
address, or to run multiple bgpd processes on one host.
+.. option:: -n, --no_kernel
+
+ Do not install learned routes into the linux kernel. This option is useful
+ for a route-reflector environment or if you are running multiple bgp
+ processes in the same namespace. This option is different than the --no_zebra
+ option in that a ZAPI connection is made.
+
+.. option:: -S, --skip_runas
+
+ Skip the normal process of checking capabilities and changing user and group
+ information.
+
+.. option:: -e, --ecmp
+
+ Run BGP with a limited ecmp capability, that is different than what BGP
+ was compiled with. The value specified must be greater than 0 and less
+ than or equal to the MULTIPATH_NUM specified on compilation.
+
+.. option:: -Z, --no_zebra
+
+ Do not communicate with zebra at all. This is different than the --no_kernel
+ option in that we do not even open a ZAPI connection to the zebra process.
+
+.. option:: -s, --socket_size
+
+ When opening tcp connections to our peers, set the socket send buffer
+ size that the kernel will use for the peers socket. This option
+ is only really useful at a very large scale. Experimentation should
+ be done to see if this is helping or not at the scale you are running
+ at.
+
+LABEL MANAGER
+-------------
+
+.. option:: -I, --int_num
+
+ Set zclient id. This is required when using Zebra label manager in proxy mode.
