Hi, I'm installing an 877 on an ADSL line. The config is as follows:
interface ATM0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0.1 point-to-point
ip address 100.0.2.2 255.255.255.252
ip virtual-reassembly
no snmp trap link-status
atm route-bridged ip
pvc 0/40
protocol ip 100.0.2.1 broadcast
encapsulation aal5snap
!
!
interface FastEthernet0
!
interface FastEthernet1
!
interface FastEthernet2
!
interface FastEthernet3
!
interface Vlan1
ip address 192.168.1.253 255.255.255.0
!
ip route 0.0.0.0 0.0.0.0 100.0.2.1
The DSL line is up, protocol up, interfaces are all green.
ping atm interface atm0.1 0 40
Type escape sequence to abort.
Sending 5, 53-byte end-to-end OAM echoes, timeout is 2 seconds:
!!!!!
BUT, I cannot ping myself!!!
ping 100.0.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.0.2.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
Tried several configs, consulted with the DSL line provider, doesn't work. Can't ping myself and can't ping the gateway..
Any ideas?
Solved! Go to Solution.

Thanks, that helped to see my own IP!
Nevertheless, now I cannot ping the gateway (100.0.2.1) - the other end of the point to point link. The physical connection exists, the line is OK, the ISP checked their side, the gateway is OK. They can't ping me also.
Is there some kind of feature that needs to be turned on on the bridge interface? Besides the "bridge 1 route ip"?
Thanks

Not really. Please send again the config, and output of "show atm pvc 0/40", "show bride 1 detail".

Hi,
you never receive any packet on PVC 0/40, check with ISP that it is correctly provisioned. Have them ping your address, if counter doesn't increase, something is wrong.

The ISP had an error. Now everything works.
Thank you for your help!

Yes, routers don't lie.
Good luck and Season Greetings!
