The experiments listed this time are supplementary exam questions, the main points of assessment are
1, basic ip configuration
2, ospf and static routing configuration
3, basic configuration of IBGP-EBGP
4, basic knowledge of BGP transfer routing, I for I, E for I Whether the next hop changes
Requirements:
1. AR1\AR9\AR10 accesses through the default route
2. AR3\AR6\AR8 accesses the network behind AR1\AR9\AR10 through the static route
3. BGP100 and BGP200 use ospf to establish internally
4. The two ASs establish EBGP transfer routes
5. Finally, pc1 successfully accesses servers 1 and 2.
