BGP and IGP Synchronization Configuration

Network requirements
As shown below, all devices of company A belong to AS 65008 while all devices of company B belong to
AS 65009. AS 65008 and AS 65009 are connected through Switch A and Switch B. It isi required that
Switch A can access network 9.1.2.0/24 in AS 65009, and Switch C can access network 8.1.1.0/24 in
AS 65008.

Configuration procedure
1) Configure IP addresses for interfaces (omitted)
2) Configure OSPF
Enable OSPF in AS 65009, so that Switch B can obtain the route to 9.1.2.0/24.
# Configure Switch B.
<SwitchB> system-view
[SwitchB] ospf 1
[SwitchB-ospf-1] area 0
[SwitchB-ospf-1-area-0.0.0.0] network 2.2.2.2 0.0.0.0
[SwitchB-ospf-1-area-0.0.0.0] network 9.1.1.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.0] quit
[SwitchB-ospf-1] quit
# Configure Switch C.
<SwitchC> system-view
[SwitchC] ospf 1
[SwitchC-ospf-1] import-route direct
[SwitchC-ospf-1] area 0
[SwitchC-ospf-1-area-0.0.0.0] network 9.1.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.0] quit
[SwitchC-ospf-1] quit
3) Configure the eBGP connection
Configure the eBGP connection and inject network 8.1.1.0/24 to the BGP routing table of Switch A, so
that Switch B can obtain the route to 8.1.1.0/24.
# Configure Switch A.
<SwitchA> system-view
[SwitchA] bgp 65008
