P - Passive Indicates that no EIGRP computations are being performed for this destination.
A - Active Indicates that EIGRP computations are being performed for this destination.
U - Update Indicates that an update packet was sent to this destination.
Q - Query Indicates that a query packet was sent to this destination.
R - Reply Indicates that a reply packet was sent to this destination.
r - Reply status A ?¬‚ag that is set after the software has sent a query and is waiting for a reply.
172.16.90.0 Destination IP network number.
255.255.255.0 Destination subnet mask.
successors Number of successors. This number corresponds to the number of next hops in the IP
routing table. If ???successors??? is capitalized, the route or next hop is in a transition
state.
FD Feasible distance. The feasible distance is the best metric to reach the destination or
the best metric that was known when the route went active. This value is used in the
feasibility condition check. If the reported distance of the router (the metric after the
slash) is less than the feasible distance, the feasibility condition is met and that path
is a feasible successor. After the software determines it has a feasible successor, it
does not need to send a query for that destination.
