Lab 6-3 Configuring IBGP and EBGP Sessions, Local Preference and
Friday, November 14, 2008
Learning Objectives
In this lab, you will configure both IBGP and EBGP. For IBGP peers in this lab to correctly exchange routing information, the next-hop-self command must be
used along with the Local-Preference and MED attributes. This is to insure that the flat-rate, unlimited-use T1 link is used for sending and receiving data to and from the AS 200 on ISP. The metered T1 should only be used in the event that the primary T1 link has failed. Traffic sent across the metered T1 link offers the same bandwidth of the primary link but at a huge expense. Ensure that this link is not used unnecessarily.
Scenario
The International Travel Agency runs BGP on its SanJose1 and SanJose2
routers externally with ISP, AS 200. IBGP is run internally between SanJose1

and SanJose2. Your job is to configure both EBGP and IBGP for this
internetwork to allow for redundancy.
