as number:local, where as-number is an AS number and local is a locally-significant number
between zero and 65535. Alternately, well-known communities may be specified by name:
NO_EXPORT, NO_ADVERTISE, NO_EXPORT_SUBCONFED, or NO_PEER.
localpref number
Set the LOCAL_PREF AS path attribute. If number starts with a plus or minus sign, LOCAL_
PREF will be adjusted by adding or subtracting number; otherwise it will be set to number.
med number
metric number
Set the MULTI_EXIT_DISC AS path attribute. If number starts with a plus or minus sign,
MULTI_EXIT_DISC will be adjusted by adding or subtracting number; otherwise it will be set to
number.
nexthop (address|blackhole|reject|self|no-modify)
Set the NEXTHOP AS path attribute to a different nexthop address or use blackhole or reject
routes. If set to no-modify, the nexthop attribute is not modified. Unless set to self, the nexthop
is left unmodified for IBGP sessions. self forces the nexthop to be set to the local interface
address.
set nexthop 192.168.0.1
set nexthop blackhole
set nexthop reject
set nexthop no-modify
set nexthop self
pftable table
Add the prefix in the update to the specified pf(4) table, regardless of whether or not the path
was selected for routing. This option may be useful in building realtime blacklists.
prepend-neighbor number
Prepend the neighbor’s AS number times to the AS path.
prepend-self number
Prepend the local AS number times to the AS path.
rtlabel label
Add the prefix with the specified label to the kernel routing table.
weight number
The weight is used to tip prefixes with equally long AS paths in one or the other direction. A
prefix is weighed at a very late stage in the decision process. If number starts with a plus or
minus sign, the weight will be adjusted by adding or subtracting number; otherwise it will be set
to number. Weight is a local non-transitive attribute and a bgp-specific extension.
