How do route installation and packet forwarding differ?
Back
Route installation determines which routes enter the routing table; packet forwarding uses a packet’s destination address to choose among installed routes.

02
Front
What does a routing protocol metric compare?
Back
A routing protocol’s metric compares paths that the protocol has learned to the same destination.
03
Front
Which path does OSPF prefer?
Back
OSPF prefers the path with the lowest total cost.
04
Front
What does administrative distance compare?
Back
Administrative distance (AD) chooses between different sources offering the same prefix; the lower AD is preferred.
05
Front
What are common Cisco IOS default ADs for connected, static, OSPF, and RIP routes?
Back
Common Cisco IOS defaults are connected 0, static 1, OSPF 110, and RIP 120. Values can vary by platform or configuration.
06
Front
Which route wins if static and OSPF both offer 10.20.0.0/16?
Back
The static route is preferred because its default AD of 1 is lower than OSPF’s default AD of 110.
07
Front
What does [110/25] mean on an OSPF route?
Back
The route has AD 110 and metric (OSPF cost) 25.
08
Front
How does longest-prefix matching choose a route?
Back
Longest-prefix matching (LPM) selects the matching installed route with the largest prefix length.
09
Front
Which route matches 10.20.1.7: 10.20.0.0/16 or 10.20.1.0/24?
Back
The router selects 10.20.1.0/24 because it is the longest matching prefix for that destination.
10
Front
Which specific route matches 10.20.8.7: 10.20.0.0/16 or 10.20.1.0/24?
Back
The router selects 10.20.0.0/16 because 10.20.1.0/24 does not match 10.20.8.7.
11
Front
When may a router use its default route?
Back
A default route may be used when the destination matches neither of the more-specific routes.
12
Front
How are equal-prefix paths compared within one routing protocol?
Back
Within a routing protocol, compare its metric to identify the preferred path. Equal-cost paths may be installed together if the platform supports them.
