+ - replicated route, % - next hop override
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, Dialer1
10.0.0.0/32 is subnetted, 2 subnets
C 10.0.0.1 is directly connected, Dialer1
C 10.0.0.254 is directly connected, Dialer1
h. Issue a show pppoe session on Cust1 router. Sample output is shown below.
Cust1# show pppoe session
1 client session
Uniq ID PPPoE RemMAC Port VT VA State
SID LocMAC VA-st Type
N/A 1 30f7.0da3.0b01 Gi0/1 Di1 Vi2 UP
30f7.0da3.0bc1 UP
i. Issue a ping to 10.0.0.254 from the Cust1 router. The ping should be successful. If not, troubleshoot until
you have connectivity.
Cust1# ping 10.0.0.254
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.254, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
