Configuring BGP to Import Routes
Configuring BGP to Import Routes
Context
BGP cannot discover routes and needs to import routes
such as IGP routes into BGP routing tables so that the imported routes
can be transmitted within an AS or between ASs. BGP imports routes
in either import or network mode:
In import mode, BGP imports IGP routes, including RIP, OSPF,
and IS-IS routes, into BGP routing tables based on protocol type.
To ensure the validity of imported IGP routes, BGP can also import
static routes and direct routes in import mode.
In network mode, BGP imports the routes in the IP routing table
one by one into BGP routing tables. The network mode is more accurate
than the import mode.
