The problem:

R3 was configured to send to BB1 only routes originated in AS3. So only R3 can ping BB1 from its Lo0. However, its not working, as no router can ping BB1 from it's Lo0. Find and fix the problem.

Ticket 1
R2 can’t ping R6’s Lo0 interface from it’s Lo0.

Ticket 2
R6 can NOT ping BB1’s Lo0, which is 21.21.21.21. You should fix this problem without changing R6’s routing table.

Ticket 3
R6 can’t ping R2’s F0/0. You should fix this problem using a single interface configuration command. DO NOT use a global config command to resolve this problem.

Ticket 4
R2 can NOT ping R5’s F0/0.

Ticket 5
R5 can NOT ping R4’s Lo0.

Ticket 6
R4 can NOT ping R1’s or R3’s Lo0.

Ticket 7
R6 is configured to join 239.6.6.6. R4 can NOT ping this group address. You should use an interface command on R4 to fix this problem.

Ticket 8
The following routes are sent from BB4 to R1: 24.24.24.24 /32, 24.24.24.1 /32, 24.24.24.2 /32 and 24.24.24.3 /32 R1 is configured with the following policy for routes coming from BB4:
  • R1 should be configured such that R5 does NOT advertise network 24.24.24.2 /32 to R6
  • R1 should filter network 24.24.24.1 /32 However, R5 does NOT see network 24.24.24.24 /32 and network 24.24.24.3 /32 that should have come from BB4.

Ticket 9
R6 can NOT ping 24.24.24.3. You should fix this problem without configuring BGP or any redistribution.

Ticket 10
R6 is configured to ONLY allow R2 to Telnet to BB1, R2 can NOT Telnet to BB1. You should fix this problem while keeping the policy.
