Arguments:

• to SELECTOR (default)

  -- only select routes from the given range of destinations. SELECTOR consists of an optional modifier (root, match or exact) and a prefix. root PREFIX selects routes with prefixes not shorter than PREFIX. F.e. root 0/0 selects the entire routing table. match PREFIX selects routes with prefixes not longer than PREFIX. F.e. match 10.0/16 selects 10.0/16, 10/8 and 0/0, but it does not select 10.1/16 and 10.0.0/24. And exact PREFIX (or just PREFIX) selects routes with this exact prefix. If neither of these options are present, ip assumes root 0/0 i.e. it lists the entire table.

• tos TOS or dsfield TOS

  -- only select routes with the given TOS.

• table TABLEID

  -- show the routes from this table(s). The default setting is to show table main. TABLEID may either be the ID of a real table or one of the special values:

  • all -- list all of the tables.
  • cache -- dump the routing cache.
  1cm NB. IPv6 has a single table. However, splitting it into main, local and cache is emulated by the ip utility.

• cloned or cached

  -- list cloned routes i.e. routes which were dynamically forked from other routes because some route attribute (f.e. MTU) was updated. Actually, it is equivalent to table cache.

• from SELECTOR

  -- the same syntax as for to, but it binds the source address range rather than destinations. Note that the from option only works with cloned routes.

• protocol RTPROTO

  -- only list routes of this protocol.

• scope SCOPE_VAL

  -- only list routes with this scope.

• type TYPE

  -- only list routes of this type.

• dev NAME

  -- only list routes going via this device.

• via PREFIX

  -- only list routes going via the nexthop routers selected by PREFIX.

• src PREFIX

  -- only list routes with preferred source addresses selected by PREFIX.

• realm REALMID or realms FROMREALM/TOREALM

  -- only list routes with these realms.
