The column headings in screens invoked by the ip command have the following
meanings:
* (asterisk) Indicates routes actively used by IP, versus routes not currently
used. (The asterisk appears only when you specify the all routes
[-A] flag.)
Adv Router Indicates the OSPF Router ID of the advertisement's originator.
For router links advertisements, this field is identical to the Link
State ID field. The network’s Designated Router originates
Network Link advertisements. Area border routers originate
Summary Link advertisements. AS boundary routers originate AS
External Link advertisements.
Age Number of seconds since this route was last updated or verified to
be correct. The meaning of “too old” depends on the routing
protocol specified under Proto. Note that RIP and EGP routes are
refreshed only on a slot that receives a routes update. Route ages
may be different on each slot for this reason.
ASE Fwd Addr An address for forwarding packets to a destination external to the
AS, but not accessible through an AS boundary router.
Cost Number of hops to reach the destination.
Link State ID (LSID) Indicates the piece of the routing domain that the advertisement
describes, as follows:
If LS Type = 1, LSID = the originating router's Router ID.
If LS Type = 2, LSID = the IP interface address of the network's
Designated Router
If LS Type = 3, LSID = the destination network's IP address.
If LS Type = 4, LSID = the Router ID of the AS boundary router.
If LS Type = 5 , LSID = the destination network's IP address.
Loc Pref A discretionary attribute used by a BGP speaker to inform other
BGP speakers in its own autonomous system of the originating
speaker's degree of preference for an advertised route.
LS Type Indicates the type of OSPF Link State advertisement, as follows:
0 = stub advertisement
1 = router links advertisement
2 = network links advertisement
3 = summary link (IP network) advertisement
4 = summary link (ASBR) advertisement
5 = external link advertisement
Refer to RFC 1583 for more information on LS Type.
