This was given by my friend and i cannot touch any of the configuration of the ISP router in the middle. but i have screenshots of routing table and interfaces.
pinging the middle router from HOST A and getting intermittent connection i am not sure what would be the cause of this.
this is the running-config or ROUTER 12 which connects to ISP:
ACL1#sho run Building configuration... Current configuration : 778 bytes ! version 15.1 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname ACL1 ! ip cef no ipv6 cef ! license udi pid CISCO2911/K9 sn FTX15241JMW ! spanning-tree mode pvst ! interface GigabitEthernet0/0 ip address 192.168.100.2 255.255.255.252 duplex auto speed auto ! interface GigabitEthernet0/1 ip address 172.22.242.30 255.255.255.240 duplex auto speed auto ! interface GigabitEthernet0/2 ip address 192.168.33.254 255.255.255.0 duplex auto speed auto ! interface Vlan1 no ip address shutdown ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.100.1 ! ip flow-export version 9 ! line con 0 ! line aux 0 ! line vty 0 4 login ! end
thank you so much for help..
