Tab le 7 Description of A-P-O in the IS-IS Link State Database
Heading Meaning
A The Attach bit. Indicates that the router is also a Level 2 router, and it
can reach other areas. Level 1 routers, and Level 2 routers that have lost
connection to other Level 2 routers, used the Attach bit to find the
closest Level 2 router.
P The P bit. This detects if the IS is “area partition repair” capable.
O The Overload bit. This determines if the IS is congested. If the Overload
bit is set, other routers do not use this system as a transit router when
calculating routes. Only packets for destinations directly connected to
the overloaded router are sent to this router.
