lab 9-11-2020 bgp local pref

[Marco Bonola < >]

Dear students,

please find attached the configuration files for the lab we did today.


HOMEWORK:

1) add R8 into AS 40

2) configure IP addresses

3) configure OSPF

4) configure BGP

5) change the current iBGP configuration and instead of creating an iBGP 
full mesh make R4 the route reflector for AS 40

6) test if everything works


Ciao

Marco
