Parameter Description
Origination of You can enable a router to originate default routes for
default routes the following route exchange protocols, on an
individual protocol basis:
• RIP
• OSPF
• BGP4
Default route Optimizes forwarding cache space by aggregating
aggregation cache entries for destinations to which the router
forwards traffic using a default route. When you
enable default route aggregation, the router makes a
single cache entry for a destination network instead of
multiple entries for the hosts on the network.
Default network The router uses the default network route if the IP
route route table does not contain a route to the destination
and also does not contain an explicit default route
(0.0.0.0 0.0.0.0 or 0.0.0.0/0).
Static route An IP route you place in the IP route table.
Source interface The IP address the router uses as the source address
for Telnet, RADIUS, or TACACS/TACACS+ packets
originated by the router. The router can select the
source address based on either of the following:
• The lowest-numbered IP address on the
interface the packet is sent on.
• The lowest-numbered IP address on a specific
interface. The address is used as the source for
all packets of the specified type regardless of
interface the packet is sent on.
