Configuration Guide - IP Routing

Network Requirements

As shown in
Router D and Router E. IBGP full connections are established between partial routers in AS 10,
and OSPF is used as an IGP protocol.
It is required to enable OSPF-BGP linkage on Router B so that the traffic from Router A to AS
20 is not interrupted after Router B restarts.

RouterA
POS1/0/0
POS1/0/0
10.1.1.2/30
Enable OSPF on Router A, Router B, Router C, and Router D (except 10.2.1.1/30) and
specify the same area for all OSPF interfaces.
Establish IBGP full connections between Router A, Router B, Router C, and Router D
(except 10.2.1.1/30).
Set the OSPF cost on Router C.
Establish the EBGP connection between Router D and Router E.
Configure the OSPF routes and configure BGP to import directly connected routes on
Router D.
Configure BGP on Router E.
The router ID of Router A is 1.1.1.1, the AS number is 10, the OSPF process number is 1,
and the network segments in Area 0 are 10.1.1.0/30 and 10.1.2.0/30.
