first of all thank you cciereallabworkbook for workbook
Ticket 1 : sw1 had port-security and sticky mac address, i changed the mac-address
Ticket 2 : R17 didnt get the ip address, username and password were true but dhcp pool configuration on R12 was faulty
Ticket 3 : there was area range command i changed it with area range 134.56.78.48 255.255.255.252
Ticket 4 : distribute-list deny R14 loopback
Ticket 5 : BGP question was almost same
Ticket 6 : there was ipv6 filter-list and question was state that you shouldnt change traffic filter, R25 did not have route-map, i created route-map NH and defined next-hop address
Ticket 7 : R19 could not establish eigrp neighborship with R15, changed ip nhrp map multicast address
Ticket 8 : this question was different, i almost spend 30 minutes with this, topology etc. same but, i did not reache the 172.16.201.0 subnet which is connected to the R10, on R8 i have applied “neighbor 125.45.67.26 default-originate route-map MED” command, i lost many time with this question but i solved it.
Ticket 9 : it was working, i didnt change anything
Ticket 10 : nat access-list was access-list 10 permit host 192.168.1.0 , i changed it with access-list 10 permit 192.168.1.0 0.0.0.255
