Verify that ACME1 has properly formed an eBGP adjacency with ISP1.Use the 1.1.1.9 as the neighbor IP address of ISP2 and make sure to add Other Company’s internal network 172.16.10.0/24 to BGP. Other Company is under AS 65002 while ISP is under AS 65003. You must also configure their end of the connection.Ĭonfigure OtherCo1 to form an eBGP adjacency with ISP2, the ISP border router facing OtherCo1. The network administrator at Other Company is not familiar with BGP and could not configure their side of the link.
Step 2: Configure eBGP in Other Company Inc. Use the 1.1.1.1 as the neighbor IP address and make sure to add ACME’s internal network 192.168.0.0/24 to BGP.ĪCME1(config)# router bgp 65001 ACME1(config-router)# neighbor 1.1.1.1 remote-as 65003 ACME1(config-router)# network 192.168.0.0 mask 255.255.255.0įrom any device inside ACME’s network, ping the Other Company internal server again.
ACME’s AS number is 65001, while the ISP is using AS number 65003.
Configure ACME1 to become an eBGP peer with ISP1. The pings should fail as no BGP routing is configured at this time. From any device inside ACME’s network, ping the Other Company’s server 172.16.10.2. #PACKET TRACER ACTIVITY 3.5.3 SERIAL#
Verify that the ISP has provided IP reachability through its network by pinging 1.1.1.9, the IP address assigned to ISP2’s Serial 0/0/0. Because ISP is using BGP as the routing protocol, you must configure ACME1, ACME’s border router, to establish a BGP neighbor connection with ISP1, the ISP border router that faces ACME. You must connect ACME to the ISP so that ACME and Other Company can communicate. The ISP has established network reachability within its network and to Other Company. hired an ISP to connect to a partner company called Other Company. Note: Only companies with very large networks can afford their own autonomous system. Both companies have their own autonomous systems and will use ISP as the transit AS to reach each other. is a company that has a partnership with Other Company and must exchange routes. In this activity, you will configure and verify the operation of eBGP between autonomous systems 6502. 3.5.3.4 Packet Tracer – Configure and Verify eBGP ObjectivesĬonfigure and verify eBGP between two autonomous systems.
