IP Routing—Configuring RIP, OSPF, BGP, and PBR
Quick Start
13-176
Quick Start
This section provides the commands you must enter to quickly configure:
RIP
OSPF:
•
internal router
•
ABR
•
ASBR
BGP
You can use more than one routing protocol. When the router learns identical
routes through different routing protocols, it uses the administrative distances
shown in Table 13-28 to choose between them.
This section also includes the commands for configuring a route map for PBR.
Because the configuration of PBR is, by definition, dependent on your orga-
nization's policies, the quick-start commands are quite general.
Only a minimal explanation is provided. If you need additional information
about any of these options, check "Contents" on page 13-1 to locate the section
that contains the explanation you need.
